If you are after a really cheap chess board, be it for starting out with chess or for situations where you don't want to carry around an expensive and heavy board, these vinyl boards are a great choice. Made from vinyl, they are dirt and water resistant - you can wash them if they get dirty and if you spill your morning coffee over it, they will forgive it. Of course they are also flexible so can easily be rolled up and stored away and are also great to carry them with you, say, for a play outdoors, in your garden or a park.
The square size of these boards is 55mm and that makes them suitable for chess pieces with a 43mm base diameter (for the king). The overall size of these vinyl boards are 50 x 50cm.
This two-in one vinyl board has a print for playing mills on the back side. If you don't want a double-sided printed board, then you save a bit by buying the Vinyl Chess Board.
