A couple years ago I switched all stamp storage to the Stamp-n-Storage stamp cards and envelopes. They are much, much better than the DVD style cases I used to use. With these, I have easy access and can quickly view my stamps without removing them from the envelope. Then, the slimline card craze begins. Uh-oh! I made a suggestion to Stamp-n-Storage that they create stamp & die storage for the new slimline size. Others must have suggested the same because now we have the new, taller size stamp cards, die magnet cards, and envelopes. I love them! The tall cards provide an excellent support system for slimline stamps and dies. Thank you for the great products!
