Create spherical ice for chilling and garnishing cocktails, water, iced tea and other refreshments with Zoku Silicone Ice Sphere Molds (set of 2). The uniform balls of ice melt slowly and evenly to keep drinks colder longer with less dilution. Easy to use, the silicone molds invert so you can easily remove the ice sphere without having to rinse under water. Just pull the halves apart, flip over the mold, and push on the bottom of the mold to release a perfect 2-1/2" diameter ice ball. BPA and Phthalate-Free, the ice molds are dishwasher safe and stack for easy storage.
