Conventional folding boards have a hinge at the center, which means that they do not lie fully flat when opened out.
The two sides of this folding board are connected by a cloth lining so that the board lies completely flat for a stress-free game.
This reversible set has 19 lines on one side and 9 on the other.
During a game：42.5×45.5×1.3
When folded up：21×45.5×2.6
