This is an open deck box that can hold 100 sleeved cards for a commander deck. There is a slot in front to hold your commander card and larger slot in back to hold the rest of the deck with a little extra room for things like token cards. Also included is cap for the top. Note that when printing the cap it may be a tight fit so feel free to increase the dimensions slightly before printing to get that nice snug fit.
