This top measures about 4" x 4.5" and weighs in at 194 grams (6.8 oz). Made from dowel reinforced laminations of ColorPly, thin black veneer, Amboyna burl and Delrin plastic. Its hollowed out to a 3/8" wall thickness, to reduce topside weight and allow for internal cord storage. The button is a customized fractal-themed poker chip, that doubles as a lid in case you want to think of this as a box.
