These are the perfect envelope for my ATC cards. I love making my own on cardstock for all occasions and giving them to people. I've been using regular size env or those from $1 Store thank notes. I love the colors. I don't need them to be super sturdy. The are perfect. They cannot be mailed, though. I believe the minimum size for USPS requirements is 3.5" x 5.5". This was also the best bargain for the amount. Super pleased with this product. So glad I found you!
I had gift cards from a coffee shop, but they were out of their envelopes. I founds these and they are perfect. Just the right size, lots of colors and good quality. Easy transaction. They came right away.
