Designed for schools, gym classes, and recreational play, the Throw Down Base Set creates an instant baseball diamond on virtually any surface. Made from molded vinyl, these easy-to-clean bases will not mark floors, making them ideal for indoor use. The vinyl construction naturally grips the surface to help reduce slipping and unintended movement during play. This bright orange 4-piece set includes three bases and one home plate, with each base measuring 17 inches long x 17 inches wide. Sold as a complete set.
