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

I ordered these bubble post boxes to send out photo packages from an event, they were large enough for 8x10 prints and card stock. The seal was very tight, I expected to have to use shipping tape to make them more secure for shipping. I printed my own mailing labels and attached them to each mailing list and they stuck to mailers very well. Purple is my signature color so I really liked it when I found them, they arrived on the promised day and were well packaged.
