The Fantastic Folding Dice Tray, Elder Dragon

Featuring a superior, textured, and reversible, vegan leather underbelly and a luxuriously smooth vinyl rolling surface, this tray provides more than enough room for even the chonkiest of dice, giving that soft and secure place to tumble away into natural '20s. The newly improved vertical sides also offer more rolling real estate, whilst taking up less table space. Utter magic. 

Once the battle is over, it collapses down to just under the size of an A4 page so that it can be stowed away next to your RPG sourcebooks, or into the box of a board game until your next adventure.
