Coal for board games (30 token upgrades for Brass Birmingham, Lancashire etc)

A set of 30 mini coal pieces to use in board games (Brass Birmingham, Lancashire etc)

The material used is stone, but not actual coal, so it is heavy and gives a very realistic feel yet it does not stain like coal would.

The set is made from natural materials, which means each piece has different shape and slightly different size (10-15mm)
The stones are hand picked to make sure the size differences are not too big.
