Fiberglass sticks
Available in wood color, green, white and black. Glass fibers are pulled through a bath of polyester resin and harden into their final shape. This makes the sticks strong, lightweight and corrosion-resistant.
Rubberwood
Available in natural and dark. Rubber trees are reused for their wood after about 25 years of producing rubber. The wood has a light color, is very stable and shrinks very little. It is treated with clear or dark wood oil, and you can repeat this treatment over time.
Natural rubber
Natural rubber is pale. The black color comes from adding carbon, silica or chalk before it is cured. The chalk can leave black marks on the floor, but they are easy to remove.
