Review on UCGOU 10 5X16 Envelopes: Waterproof and Tear-Proof Solution for Secure Sending by Alexander Scharon

I bought these to use for my eBay business and they are working well so far (no one has complained about their items being delivered damaged or anything), but I'm a bit scared of it after mailing a heavier item (book) in one of them. I picked up the package after it was ready to ship and because it was heavier I had to pack it tighter. To my surprise, I found the bubbles bursting. I have NEVER experienced this with any of my other mailboxes. In fact, I snagged a few of my eBay tokens and actually drove into town to get them out, but they just wouldn't come out, so the pop wasn't just for putting a heavier item in. I think this is the biggest deal in the world? no I still like email programs. The color is bright. They are good and large. They close very tight. The stitching seems strong so I'm not worried about it falling apart in transit. But still, I don't think bubbles should burst that easily, and it's definitely worth mentioning. If I pay to have bubbles shipped, I expect the bubbles to remain intact. All in all I would probably buy them again. I just can't send in heavier items anymore.
