I agree, accept no substitute. I use a strict system of rules, refined over decades of gaming, concerning Crown Royal dice bags.
1. You must first empty the dice bag.
2. A bottle with liquid in it must remain in its bag, for its own protection.
3. Once the bottle can safely be removed, place your dice in the bag.
4. Take care of your bag, keep it in the floor in a corner, use the empty bag as a drink coaster during the game, wet it slightly and use it wipe marker off the battlemat. If desperate, use it for personal hygiene situations (runny nose, split lip).
5. A bag that becomes fouled in any manner is not a proper receptacle for dice. If your bag picks up a water mark, a stain, a bit of bodily fluid, a smudge of ink from a wet erase marker, etc., the bag must be discarded and rule 6 implemented as quickly as possible.
6. Replace your fouled bag with a new Crown Royal bag from the store. Move back to Rule 1.
