Bamboo Chess SetPLA Chess is handmade in sunny San Diego, California. This chess set has a sleek, sophisticated appearance, putting a modern twist on a traditional game. PLA Chess uses quality materials. The board is made out of bamboo, laser engraved with a polygonal texture to compliment the look of the chess pieces and finished with a satin top coat. Pieces are hand casted in resin or 3D printed and weighted. They have a smooth finish, easy to hold. Why bamboo?
