The Tovolo Watermelon Stackable Ice Pop Molds Set of 4 turn juice, yogurt, smoothies and fruit puree into watermelon-wedge pops for summer snack time. Each mold holds 2.3 fluid ounces and measures 5.86 by 3.78 by 1.24 inches. Fill each mold to the integrated fill line, snap on the fully enclosed lid, add the stick and freeze for 4 to 6 hours. The lids prevent spills and keep freezer odors out, so every batch tastes the way you made it. When the pops are ready, the flexible silicone releases each one cleanly. Long handles with built-in drip guards catch melting drops before they reach little hands. The four molds stack into a compact tower that saves room in the freezer. Everything is BPA-free, the silicone will not absorb flavors, and the molds go right into the dishwasher.
