Bottomless card box

Jenna and I found some unfinished Wooden Cigar type boxes the perfect size to hold invitation size cards and envelopes. An awesome gift idea came to me and we are both excited about it. It was inspired by the bottomless coffee idea. We snatched up 10 and are going to make bottomless gift boxes filled with cards. Each box will be painted and decorated to suit the recipient. It will be filled with an assortment of cards. Attached to each box will be a note letting the recipient know it is a bottomless box of cards. If it is returned to us empty, Jenna and I will refill it. Have to work on the note and will post when we have one finished.
If you have an idea please leave it in the comment section.
