Made with high-quality nylon, it prevents the dirt from the floor from sticking to the caster thus ensuring a smooth balanced roll. It is very easy to install and immediately makes the furniture look new and increases the overall height by 2 inches. Since it is nylon, the wheels are very easy to clean and the strongest plastic is used for casters.
