I went to Joann Fabrics today. I came across this photo case that holds 100 4 x6 pictures. It was 1.99 with 40% off coupon it came to 1.19. Any way I have been looking of a way to store my stamps. I took the stamps I got from MPS and pulled off the sheet with the pictures of the stamps and put it on the outside of the case. I also did the same to the back with another set. It was the perfect fit. Then I put the stamps on the inside to match where the pictures were. The case locks shut so now It is so easy to get my stamps and not lose them. No more struggling with trying to get them out of the sleeve.
