Mystery Gacha D20

How about a surprise d20? Take a chance and get a numbered or logo d20! It's all the excitement of gachapon, with none of the chances of getting the same thing twice (man, that's the worst!). And if you get the golden d20, you win a free set!

(Feel free to add some colors or vibes you like in the seller's note if the mystery part is a little too nerve-wracking!)
