You've encountered a Random Encounter accessory. This vinyl dice box contains storage space for one set of a 7 piece dice set.
Extremely durable, this box will protect your most prized dice set within your collection. The lid closes using 2 magnets, meaning those dice won't just fall out into the bottom of your bag of holding.
Disclaimer: We take no responsibility if you roll a natural 1 on closing this box correctly, thus causing the dice within to infact fall out into the bottom of your bag of holding.
