The Short Stem Corian top is made by Harry Kramer. Corian is a material often used for counter tops and is made from certain types of plastics combined with aluminum. The top shown in the picture above is sold, but we also have two more of the same design, one white, the other a navy blue. Color sent will be random, unless specified by e-mail at time of purchase. Each top has flecks of color. It is an excellent spinner as well. It is 37mm in diameter.
