The Classic II is made of Arcel�, a tough new copolymer of expandable polyethylene from Nova Chemicals. Like the Classic, the Classic II features zero maintenance, has a soft surface for safety, and yet is even more resistant to nicks and dents. The smooth polyethylene surface is particularly easy on people with sensitive skin. The Classic II is made with a swirled pattern of blue and white or green and white. Each board is unique.
