I wanted to get my 4yr old a wallet to keep his library card in and the cash that he gets from his grandparents for when we go to the toy store for him to spend it. For the money it works really well and bills do fit in it and it closes nicely. His library card, however, does not. I even tried trimming the card along all four sides to make it smaller, but it still wouldn't fit once I got it down to the smallest I could make it and still have the bar code and library info on the back. This means that standard gift cards aren't going to fit, either. I will say that it folds up nicely and fits perfectly in his little size 4 jeans back pocket though. our library offers keychain cards as well as full sized credit card style cards, so that's what he's ended up putting in the wallet.
