ok so lets be real, i think the offical xanathar plush/dicepouch thing is mad ugly and it's pissed me off for a long time, especially over the fact that they totally missed the ball on making the zipper on the dicepouch NOT the mouth of the beholder, so i took matters into my own hands and made my own beholder dicepouch.
4 of the 6 eyestalks are posable and the space inside the mouth can fit a standard 7 polyhedral dice set (maybe more, i only had one set of dice to check with) or you could fit some miniatures in there if you wanted!
