Perfect for shipping psa graded cards. They give me peace of mind when I have to ship expensive shiny cardboard.
It truly has been a great help in eliminating the lost and damaged envelopes in the USPS system. One of the best products I have bought to help my sports card delivery. A+ 10 out of 10.
Absolutely phenomenal I will be a continued purchaser
They the best envelopes that I have ever received and used.
