One person said he “forgets” them in his pocket and gets clean dice via doing laundry. One person with memory problems does not a concensus make, my dear. 
I feel ashamed…I keep mind in the sack which came from Scrabble.
… it does in MY household… you haven’t met my wife… 
You are all wrong. The proper (and retro) way to store your dice is in a Crown Royal sack.
Sheesh.
Whoa. I never thought of that. And to think, I’ve been sitting around all this time trying to come up with an excuse to go out and buy some Crown Royal . . .
But then where will I keep my golf balls?
Yes. Now, as you drink that bottle, you might want to ask why, while you’re pushing 40, you still have D&D dice in your pocket.
“Roll Initiative…!”
I prefer to use a nice gold satin Chivas Regal bag for my MTG “kit” (a bunch of little glass beads to use as “counters” a couple 20sided dice, and one 6 sided). Now my D&D dice I keep in a pretty large suede bag my sis made for me ages and ages ago.
So is a shot of crown royal +2Str and -4Int or am I remembering wrong?
Well, fine-- but they’re hard to find in stores, and really, who can justify that kind of purchase on ebay?
