I found these adorable boxes at the Dollar Store yesterday, and thought they would make cute gifts, filled with cards & lined envelopes. They have a magnetic clasp to hold them shut, and will almost fit an A2. The inside measurements are 5 3/8W x 4½L x 1½ inches deep. I may have to make my own envelopes, but I almost always do that, anyway. They were in with their Easter stuff. Happy hunting.
