This Deck Box can hold 2 Dice(I used the dice included with some yugioh products)

It can hold up to 60 Single sleeved Japanese sized cards (It's best with 55 cards)

You need to glue the top together (Red and Blue parts are printed upside down so you can have the build plate texture face up)

I also included space for 8x2mm round magnets if you want to use them but the friction fit should be good enough

Test print plate 6 incase LID rails are to tight
