50-Piece Collectible Trading Card Storage Box - Holds 660 Cards - Perfect for Pokemon, MTG, and Sports Card Organizers - Ideal for Collectors and Gamers

Better than expected. Fold very nicely and the fit is initially quite snug when closed. Each box holds closer to 900 un-sleeved cards. My only complaint is that since they came bundled tightly together, the top and the bottom boxes in the stack were a bit bent and warped in places. But the price of buying them in a bundle is so much cheaper than individually that the loss of two hardly matters.
