The board is 6.5 inches long by 4.5 inches wide and has a non- stick polypropylene coating - the size is ideal for all your miniature work and has non slip tiny feet underneath which ensure the board does not slip when it is in use. I have been using this type of board for over 25 years and would not use any other when working with fimo and cold porcelain pastes as I find it does not stick nor does it become worn with use.
