The carrom board has been used for a year and a half. I am selling it because I have another carrom board. The carrom board frame including borders is 56"/56". The inner side is 46.5"/46.5". The carrom board border width is 4.5"/4.5". The carrom board border thickness is 1.5". The border of the carrom board is made of mahogany/siris wood. The inner side has plywood installed. The back side is nicely and densely supported with wooden netting for the plywood.
