I liked the larger size so much that I opted for the same brand for the 4x8 size. The Metronic brand seems like they use the same materials and build for all their bubble mailers. The mailers have a clean look with enough air bubbles to protect contents inside. I use this for my online retail business because it has a clean, professional look.

i really like these. they’re kinda smaller than i expected but it’s not a problem for me

This item is perfect for baseball card collectors. It gets the job done a highly recommended. This is a great buy. Don’t hesitate. Go ahead and buy them.

These are great for small items to ship. The inside have bubble wrap to protect what’s in the inside.

I was pleasantly surprised when I opened my box of bubble mailers the other day. I have repurchased these same mailers a few times now and normally the mailers that I receive are a matte black and have a silver strip on the back adhesion. I have never had any issues with that adhesion and no reports of it coming open to the receiver. That said though, my larger bubble mailers adhesion I have always enjoyed more just due to it having more stickiness compared to my smaller ones. I could tell this based on the strip on them being clear and every time I remove it, it ends up having a little reside left over and I tend to stick it to my label paper so I don't get the residue on anything. So when I opened this package up and found they have been changed to a clear strip I was presently surprised. I didn't have any issues with the back rising while my packages wait to go out over the holiday with the post office being closed and honestly they seemed to stick a lot easier. I'm not sure if is my imagination but I do hope they stay this way and it isn't some fluke.I also noticed that the packaging went from being a matte black to a semi glossy black. It doesn't seem to cause any issues with labels or stickers so I am not too worried about this change.
