Review on Valoin Ultra Pro 5x7 Card Sleeve: Premium 100pk by Ultra Pro - Ultimate Protection for Your Cards! by Will Murphy

I'm an events photographer and one of the things I do is send my clients samples of my work in these envelopes. This protects the photo from scratches and fingerprints. My customers are always stunned when I give them a secure photo and an envelope to keep everything in because the competition doesn't. It's that extra touch that keeps customers coming back for more.
