This is a parametric card holder that includes a display area for the box the cards came in. Particularly useful if you sleeved some cards and now they won't fit inside the original box anymore. Also includes an optional lid.
Tip: If you don't want to keep the whole box you can set the depth of the box to 1-2mm and insert a cutout of the front of the box instead.
