These are the giant 3-D printed D20 dice holders available from Etsy shop 3DCreationsPR. They're available in a variety of sizes and colors (including glow-in-the-dark) and range in price from $20 - $70. They don't have to be used exclusively for storing dice though. You can put anything that will fit in there. PROTIP: but not your nuts. That is a recipe for disaster. Especially if you try to screw the top on once they're in there. Is it weird to think that of all the websites in the whole world, that I care about your balls more than any of them? That is a fact. "I don't know..." You shut your convinced-me-I-have-cancer mouth, WebMD! You don't know them like I know them.
Keep going for a couple more shots.
Thanks again to Brandon W, who, for two tips in a row, gets an OREO cupcake. Well, one with a bite out of it anyway (I'm on a diet).
