These work very well! The color is sharp, and I've yet to have any trouble where their adhesive has failed during shipping. They are plastic, and plastic is bad for the enviornment.. I feel very dissapointed that there are not more eco-friendly and wallet-friendly options with as many colors available. If you're looking for a good mailer, these seal well, are sized well, are very durable and the price for each is fair, considering all those facts! If you can, I recommend promoting reusing and recycling to your customers with a label on the packaging, or what not <3

Imagine a whimsical crossover where the classic video game "Bubble Bobble" meets the practical world of bubble mailers. In this fun scenario, Bub and Bob, the adorable bubble-blowing dragons, embark on a new adventure centered around delivering packages. The game’s levels are now filled with colorful, animated bubble mailers instead of the usual bubbles. These mailers float around, carrying precious items that Bub and Bob must safely deliver to different characters in the game. As the dragons navigate through vibrant, platform-filled environments, they can use their bubble mailers to trap enemies or protect themselves from hazards, much like in the original game. Special power-ups inside the mailers add an extra layer of excitement. For instance, a glittery mailer might grant temporary invincibility, while a rainbow-striped one could provide a speed boost. The goal is to complete each level by successfully delivering all the bubble mailers to their destinations while avoiding or neutralizing enemies along the way. The combination of Bubble Bobble’s charming characters and gameplay with the unique twist of bubble mailers creates a playful and engaging experience, merging nostalgia with practicality in a delightful, imaginative way.

These are so useful in shipping items from my business of Ebay reselling. I sell some baseball cards and other small items I might find/purchase to resell. These bubble mailers offer good protection and seal well. Sometimes I do add some clear tape on the seal to make it even more secure, but it is not needed. They provide security as you can't see through them to see what's inside. Very easy to use and a nice value for the money. I have purchased them multiple times.

These are good quality bubble mailers. They are exactly what I needed and in a fun color too. It is difficult to read if you write directly onto the mailer. A White pen works well or I bought shipping labels and wrote on those instead. I would definitely buy these again.

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.
