I wanted to have a box to store all of my dice for DnD. I modeled this one after one of the Player Handbooks. The size is large enough to store 3 of the standard 7 dice Chessex Sets. Props to ClassyGoat for creating the original MTG Spell Book!
Inside Dimensions: ~4.8" long X 3.1" wide X 1.4" tall
Hinge Dimensions: large enough for a 6/32 machine screw
