the arm board is a solid 22mm thick piece of carbon fiber and is roughly 120mm x 120mm square when it arrived from the eu , i have uploaded pictures to prove it as it is not a piece of wood with a vinyl sticker on , it has 5 coats of clear and polished , the rack you see in the other picture was made by wilson b and has CF legs but the shelf that looks like CF is glass covered with vinyl , i did not put the CF armboard up as a cheap up grade as the block is expensive before the work was done,
