PICcircuit 2PCS for Stanley Boot, Silicone Bottom for Quencher Adventure 40oz 30oz IceFlow 20oz 30oz Bottle&for Hydroflask Tumbler 12-24oz for Stanley Cup Accessories Avoid Scratches&Noise

First they fit the Stanley ice flow 32oz. If that's what you're looking for this will work. They do the job and protect the cup. Worth the money. They slide in easy and come off for cleaning but not to easy. I'm happy with them.

Fits good.Good quality.

We have 2 different styles of the 40oz Stanley cups and they fit on both perfectly! Go on easy, stay in place well, and easy to take off

Worked perfectly on our Stanley 40oz mugs. They stay in place but are easily removable for cleaning and provide good protection for the base of the mug

I carry a tumbler with me almost everywhere and I was noticing that the bases were getting scratched up and looking a little rough. These are the perfect fit for my 40 oz tumblers, and though they are a bit snug in the car cup holders they are still able to fit. They are good accents for my cups, and i just rinse them out after using. I have found the best way to put them on is to turn them inside out and kind of roll them over the base of the cup. Definitely worth the $$.

Good quality, great size, but I'm disappointed in the color. I ordered RED and got more of a tomato-like Crayola red color. Too orange for me and not what I wanted, but I love the fit and how it keeps my cup safe.

Fits perfectly on my 30oz The Coldest tumbler. Seller should definitely market this product for other tumblers so people will know it fits. I'm not a Stanley's stan so I almost ignored this product but happy I took a chance. Quality is great, thick, and protects my tumbler

These silicone boots were perfect for my Stanley iceflow 20oz bottles. My bottle had taken a few falls and had become wobbly, which is why I purchased the boots. The boot immediately cured the wobble and matches the color of my cap near perfectly. It has a smooth finish and feels easy to wipe down or wash. I'll probably be purchasing in different sizes for our other bottles.

Does not fit Stanley Iceflow. Its loose. Maybe for the Quencher but not the Iceflow. Returned.

Great fit for Stanley Iceflow 40oz. Loved it.

It didn’t fit in the Stanley Iceflow 20oz

Had to return as they did not fit (too big) for my 21oz Hydroflask and similar sized T2 stainless steel bottles. Made sure to check measurements of 7.5cm stated on website too before purchasing to be certain. The purple colour was a nice and bright shade that I liked. Silicone quality looked and felt quite good but unsure without use. Wish they fit my bottles 😔

This was a birthday gift to go with a Stanley insulated tumbler and it was a perfect fit. The color was a bit darker than the original tumbler but it is a nice contrast. I love the silicone cup boots as they not only protect the tumbler but they protect the surface where you place them. I would recommend this product. I added a picture but not sure that it does it justice. At least you can see how it looks.
