This chess set is a portable "2 Go" set great for any occasion. Developed by Dr. Jeanne Cairns Sinquefield along with the Boy Scouts of America this set is small in size (about 4 inches long), with a blue case, a slim, fold-able travel board, and thin pieces to play with. When unrolled, the board is 15" x 15" with 1.6" squares and the king token is about 1.3" across.
