Have you ever gotten a card that you just loved. I did - it was this little toy shop. I really can't remember who sent it to us, but I loved it and probably had it in my stash for at least 10 years. Then one day, I got this great cigar box that had a wood sliding lid that I was able to cut a square out of in order to insert a thin sheet of clear plastic so you could see thru the card.
This was one of the first boxes that I wired. I hid the battery pack in the little gift box on top.
