METRONIC Bubble Mailers 8.5x12" Padded Envelopes Black 40 Pack Self Seal

I use these regularly for shipping books, and they’ve been fantastic. The size is just right for standard books, and the usable space actually fits what I need without feeling cramped. The padding provides great protection, and the envelopes themselves feel sturdy and well-made. I haven’t had any issues with tearing, splitting, or damage during shipping—even with heavier books. They also seal well and hold up through the mailing process, which gives me peace of mind when sending out orders. If you’re shipping books or similar items, these are a great, reliable option. I’ll definitely keep repurchasing.

I’ve purchased these Metronic Large Bubble Mailers (10.5x16", 40 Pack, Black) several times now, and they continue to be my go-to choice for shipping. They’re one of the best values I’ve found for padded mailers in this size, especially if you want a colored option without committing to buying hundreds or thousands at once. I’ve shipped hundreds of items with these mailers, and they’ve always held up well in transit. The bubble padding provides solid protection, and the envelopes are sturdy enough to resist tearing or damage during shipping. The adhesive is also reliable — I simply press it down once and never worry about it coming loose, and I’ve never had a single complaint from customers. The black color gives them a sleek, professional look, which is a nice touch if you’re shipping for a small business and want packaging that stands out a bit more than standard white mailers. If you’re looking for durable, good-looking padded envelopes at a fair price, I’d definitely recommend these.

These mailers are fantastic! They are thick and not flimsy and protect the item well. They are amazing quality and look cute. I use them to ship from my online store. I get great reviews on the packing.

These Metronic bubble mailers are excellent quality! The 8.5x12" size with an usable 8.5x11" interior is perfect for shipping documents, small items, or products safely. The padded interior provides great protection, and the black exterior looks sleek and professional. The adhesive seal is strong and reliable, and the envelopes are sturdy enough to handle multiple shipments without tearing. A 40-pack is very convenient and great value for anyone who ships frequently. Highly recommend these mailers for anyone looking for strong, reliable, and professional shipping envelopes!

These bubble mailers are exactly what I needed for my eBay store. I’d previously been buying shipping supplies from my local general store, but was paying $2 a piece for bubble mailers and $1.50 for simple padded envelopes. The cost per unit of these is much, much more appealing, and the quality is superior to what I had been using. The black color is very nice and (somewhat) unique, the glue strip is sticky and holds well, and they appear to be water resistant which is a huge plus. While they will still obviously tear if crammed too full, they do offer a little amount of stretchiness which makes larger objects easier to fit into as long as you don’t go too far. Overall I’m very happy with them and will be a regular purchaser of these for my online store.

Great for mailing, sturdy, seals well.

They are actually pretty good quality. Makes whatever i ship look genuine , and stands out from different packages. Will definitely order more soon.

These bubble mailers are a great size and work well for shipping a variety of items. The black color looks clean and professional, which is a nice bonus. They are easy to seal and hold items securely for mailing. The pack size is also a good value for the amount you get. The only downside is they are a little thin. They still work fine for lighter items, but for anything more delicate, you may want extra protection. Overall, they get the job done and are a solid option, just slightly thinner than expected.

Just started selling on eBay and these are perfect for what I need. Fits all kinds of PlayStation 1 style, Xbox and other PlayStation 2 and 3 etc size games and cases. Stick on closer flap works great and no issues. Canada Post sells a single 1 of these for $2 to $3 so for 40 for $23 that's a steal of a deal. Lol yes I said steal of a deal.

Excellent mailer! Used these to ship comics and they work amazing! Comes out way cheaper than anywhere else and for the same quality!

Great envelopes

Good product, basing 3 stars because of the packaging, just shrink wrapped but has holes in it that allowed water to enter inside.
