Upgrade tailgates and watch parties with the sports-themed Tovolo Tennis Ball Ice Molds! Using our classic sphere ice, we’ve created a slow-melting accessory for your favorite court-side drink. The easy-to-use molds feature a stable nylon base and a leak-free silicone lid. Simply fill the mold with water, insert the silicone lid gently, and freeze. Once frozen, the silicone lid glides off for easy ice removal. Relax, and enjoy a cold beverage thanks to Tovolo Sports Ice Molds.
