Handmade dice are popular, especially in the D&D community. With hot sellers on websites like Etsy, it may be tempting to reach for a unique set of handmade dice. But you do need to be careful because not all handmade dice are balanced. It can happen in both handmade and mass manufactured dice, but bubble formation can cause a die to favor landing on certain numbers. If you’re worried about bubbles/ inclusions, metal dice are your safest bet.
