White and black unglazed porcelain. The black team is dark porcelain, not gres. The base of the pieces is protected with a felt cover, for smooth moves. The chessboard is made of a 10 millimeter thick glass measuring 21.3" x 21.3". It is a special nonbreakable glass "antishock" with polished edges to prevent cuts and frosted engravings.
Special packaging with a box and foam allowing storage of the pieces.
