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!

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.

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.

Every product by Metronic I’ve used has been ultra easy to use, seal and ship with. Very happy with the durability, adhesives and ease to slide my products into. The cute exterior colors are fun too. I’ve tried to rip these but they’re too thick and the size is always a tad bit underestimated but that’s a good thing. These are so spacious I never have to worry about having enough room inside.

These are perfect for shipping books! I love the quality, and have purchased in other colors. The pigments are great and they are super sturdy!

Well made, very protective pouch for mailing books, etc. Perfect size.

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.

I love these- they are nice and thick. The adhesive sticks wonderfully, and I don’t need to use tape to seal the envelope. The bubble padding inside is on very cushiony. I feel like my packages are safe in transit. I will buy again and I recommend them.

Great envelopes

Tjr tres satisfaite colle vrm. Bien..

Fantastic quality and great price. You can trust that it won't just sky rocket!

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.

Good quality and great price. They’re well-made and sturdy. I sell and ship a lot with these and haven’t had any issues until now.
