The Tovolo Baseball Ice Molds Set of 2 make large craft ice spheres with baseball seam stitching pressed into every one. Each mold produces a 2.5 inch sphere with clear stitch detail that looks right at home in a rocks glass of whiskey or bourbon. Large spheres melt more slowly than standard cubes, keeping cocktails cold without watering them down. Fill each mold to the water line, cover it with the silicone lid and freeze for 4 to 6 hours. A brief rinse under warm water and a gentle squeeze release the ball cleanly from the flexible BPA-free silicone. Wide, stable plastic bases keep the molds level while you fill them and stack neatly in the freezer. Tight-fitting lids seal out freezer odors and prevent spills. The charcoal molds are dishwasher safe and make a fun gift for baseball fans.
