This is a dice box / tray combo. It is designed to hold two standard sized sets of polyhedral dice. The top of the box doubles as a very small dice tray. You will need 8 magnets (5x2mm discs), to keep the lid secure. Optionally, you can also add felt to the top and bottom.

The decorative top is completely optional. I have included the DND logo's from my Inspiration Tokens (www.thingiverse.com/thing:3367736). The pictures show my personal DM logo.

I use two of these boxes when I DM. Using two boxes, I can keep four full sets of dice neatly organized. The small dice trays work well for me, but I do not have an aggressive roll. If you don't have a light touch these dice trays will likely not work for you.
