Really great product. Very cost effective for my business.

Just recently started using them for shipping low-end sport cards on ebay. They are amazing

I’ve used the Shell Mailers now for over 100+ card sales and I couldn’t be happier! This is now my second order. Great look in the mail, easy to use, and protects cards very well too!

Everything worked out great. I look forward to my next purchase!

Great shipping envelops. Highly recommend.

Everything was easy to find and site was easy to navigate! Will def return for more products!
