All natural deodorant.
I have purchased this and similar ones multiple times and find them very effective even in the height of summer when engaging in physically demanding activities. It neutralises any odours keeping you smelling fine all day just after one application. Either apply to damp skin after washing or wet the stick then apply making sure the deodorant stick can dry afterwards. No nasty chemicals to leach into your body, just a natural process of eliminating such smells. This version is obviously unscented as it is an all natural product so if you want a smell so to speak, maybe look at natural scents that again follow the route of avoiding unnecessary chemicals and the potential harmful effects they can cause within your body. It does last an absolute age so is incredibly economical and leaves no marks on clothing afterwards. It takes me about a year or so to use one up so compare that to the everyday deodorants most people are accustomed to. Highly recommended.

100% effective deodorant containing *only* Potassium alum. Ideal for sensitive skin.
100% effective deodorant containing *only* Potassium alum (potassium aluminium sulfate) without any scent. For anyone with sensitive skin or otherwise getting irritated skin when using regular deodorants, replacing those with a deodorant containing Potassium alum (regardless of brand) is the ideal solution. Note, that this will only work on clean skin i.e. after having washed the skin area first and will last for around 24h to 48h. The best option is the solid stick type that needs to be wet before use and ideally rinsed and dried after use. One stick can last several months of daily use. For those who use body sprays and spray deodorants to conceal sweat or odours, this is NOT the solution ;-) Again, Potassium alum will only be effective on clean skin :-)

Plastic free
Trying to go plastic free and this seems like a good product to have. It's takes away smells but does not stop you from sweating. I'm happy I only have 4 stars as one of my bars was broken into a few pieces unfortunately.

Best ever
This natural deodorant crystal is fantastic! I've been trying to switch to more natural products, and I'm so glad I found this. I was a bit sceptical at first, as I'd never used a crystal deodorant before, but it works surprisingly well. It keeps me fresh and odour-free all day, even during hot weather or when I'm exercising. I simply wet the crystal and apply it to my underarms, and it's as effective as any conventional deodorant I've used, without any of the harsh chemicals or fragrances. I love that it's completely natural and doesn't irritate my sensitive skin. It's also incredibly long-lasting – I've been using the same crystal for several months now, and it's still going strong. It's much more economical than buying regular deodorants. My purchase from Amazon was completely smooth. The crystal arrived quickly and was packaged securely. It was exactly as described, and the price was excellent. I was a little unsure how to use it initially, but the instructions were clear and easy to follow. I'm so impressed with this natural deodorant crystal. It's effective, natural, and long-lasting. It's become a staple in my daily routine, and I highly recommend it to anyone looking for a healthier and more environmentally friendly deodorant option. Five stars!

A Journey to Underarm Enlightenment
Welcome to the band, brother. Or sister. Or cave bear with a finely tuned sense of personal hygiene. (We’re an inclusive bunch here.) We’ve been expecting you. Tonight, we shall toast your arrival with dew reverentially gathered from the moss atop Mount Freshness, where our ancestors first uncovered the arcane secrets of body odour control—right between the invention of the wheel and the discovery that sitting on a rock isn’t terribly comfortable. But let’s get down to the mystical object that unites us all. I know, I know… I was sceptical at first, too. It’s only natural to feel hesitant about entrusting such a vital element of our self-confidence and social esteem to something that looks like it’s been fished out of a glass of cola. Society doesn’t help either. We’re so used to sprays infused with alpha-male ions and gels enriched with unicorn drool that, when someone offers us a less flashy alternative, we pull the same grimace of horror and disgust we’d give that squirrel darting out of the park bin right as we’re about to chuck our rubbish in. But when something truly works, it works—and it’s only right to spread the word among our nearest and dearest. Because you wouldn’t want anyone getting anywhere near you without first acquiring this sacred knowledge, would you? But besides being effective, this product is downright beautiful—a quality largely derived from its simplicity. First, the simplicity of its composition, which boils down to a single ingredient: potassium alum. That’s it. Nothing dodgy here. You may have read some alarming article warning that when you rub alum stone on your skin, the aluminium seeps through your dermis, floods your body, causes cancer, Alzheimer’s, and even mugs your little red blood cells out of their pocket money, all while whistling a jaunty tune. Frankly, I’ve always found it curious how we obsess over such worries, while barely anyone questions—let alone acts accordingly—whether it’s actually safe to step outside in any city and breathe in the fumes from car exhausts, or to spend years sleeping far fewer hours each night than our bodies really need. But I digress… We were talking about simplicity—an attribute that also extends to the way this magical compound presents itself: a delicate crystal cylinder perched on a matching pedestal, like an icicle that’s just had the full manicure, pedicure, and possibly a facial. The same goes for how it’s used: two or three swipes under each armpit, and you’re done. If you ask me, that’s the best part of it all. There’s something deliciously primal and wild about that moment when, fresh out of the shower, you rub a chunk of rock under your arms, then stand there, upright in the middle of the bathroom, surrounded by steamy vapours, hands on hips, gaze pinned on some invisible point in the distance—as if trying to lock eyes with Fate itself and cry, “Come on then, send me the biggest mammoth you’ve got.” Sublime palaeolithic sensations aside, this little shard of pure freshness isn’t just a deodorant; it’s a multipurpose marvel. Need an after-shave that doesn’t smell like a chemical factory? Check. A remedy for acne? Done. A defence against fungi? Consider it handled. For the wanderers among us, its compact, non-liquid form makes it the ultimate travel companion, whether you're backpacking across Europe or just nipping to the gym—just toss it in your bag and set off on your next adventure with no fear of leakage or airport security tantrums. It’s practically a nomadic hygiene talisman. Plus, this thing is more durable than your New Year’s resolutions—just remember to dry it after each use. A dry crystal is a happy crystal, and in return, it’ll reward you by lasting a year or more. In short, it doesn’t hiss, it doesn’t leave white marks, it doesn’t try to fool you with imposter fragrances. It just sits there—stoic and gleaming—with the quiet dignity of an object that has nothing left to prove. So, welcome to the fold, my fellow crystal-bearer. You are now the custodian of ancient wisdom of purity. This little thing is your ticket to hygienic nirvana. Your armpits, your bathroom shelf—and perhaps even your destiny—shall be forever changed.

I was sceptical....
Wow! So I’m a sporty type of bloke who doesn’t sweat loads but, like most of us I get stinky pits if I wasn’t to shower or change my t shirt every day! I bought this because I just wanted natural and not to throw loads of spray into the environment. I also dislike the smell of many deodorants which are a bit overpowering and restrict actual sweating which obviously isn’t healthy. I read a few reviews and noted the “ do on a wet arm pit for 20 seconds or so” tip . The wet arm pit thing is a must. I get out the shower and use it ( for about ten seconds on each arm pit). It’s like rubbing a smooth pebble on your skin as it’s not all soft like traditional roll ons or wet, like the ball type ones. I did find that I ended up shaving my arm pits a bit with my beard trimmer (not very manly maybe but I actually quite like it now!) it made putting it on much easier and more pleasant. The results! Well I have to say it’s a great product. Samantha my partner had a few days of having to begrudgingly smell my armpits with the statement “ smell me Sam!, what do you think ?” This scientific test resulted in a positive result every time with no odour at all. Result ! I was so impressed I thought I’d do a test ( without sam’s knowledge ). I wore a black t shirt for a day and, being odour free I wore the same t shirt again ( plain black so Sam did t notice my rather minging test ).. on the morning of day four I detected a very sleight odour on my t shirt and decided not to push my relationship into this fourth experimental day. But it lasted three full days with no whiff whatsoever. I still sweat as normal ( not very sweaty ) which is healthy but no smell whatsoever even after running , gym , cycling etc. There is also zero white marks which I always get ( those horizontal lines on a t shirt after using spray deodorant ) no staining on black t shirts. Ok so I now live alone with the cat after Sam ran off with the postman saying she didn’t want to be part of this ground breaking science experimentation, but, I don’t smell. Two months on and the stick has hardly gone down at all. I use once a day after my morning shower and it seems not to get any smaller! I dry it after each application on the towel I use which sounds grubby but the towel has been all over my clean sparkling body anyway and the stick is hard like a rock and isn’t like a roll on. The only negative is the plastic container but! It’s still a reduction on impact to environment as it last so long and will have at least halved the amount of plastic used on my pits in a year. You can get it without the plastic and maybe my conscious will get the better of me, Probably around the time Amazon stop sending small items in boxes big enough to put my house in :-). Conclusion. Get this product if you want to have happy odour free pits and be kind to your skin and the environment. I won’t be going back to cloggy arm pit hair and white marks again :-)
