This is a unique handmade D20 dice made of resin.
This D20 has been pressured casted, this means the resin has been cured under pressure to remove bubbles.
Since this is a handmade product it may have minor flaws such as tiny scratches. However, all the flaws are aesthetic and don’t affect playability.
The photos are an example, the D20 you will get will be a little different since each of them are unique and handmade.
