Cool off all year-round, free from mess with the Stackable Star Molds from Tovolo. Arriving in a set of four detailed shapes, the innovative stackable design saves storage space in the freezer. The flexible molds are crafted from BPA-free, food-safe silicone, and makes removing popsicles a cinch. Simply blend up your ingredients, pour into the molds, freeze, and enjoy the perfectly formed frozen Stars! For the best results, run the molds under warm water to release the silicone before removal. The integrated fill line and fully enclosed lid promote mess-free popsicle creation with no leaks in the freezer. When the time comes to enjoy these homemade popsicles (or frozen adult beverages,) the long handles with built-in drip guards ensure minimal spills. The silicone sleeves create detailed pops using your favorite ingredients, providing a tight seal that results in mess-free frozen treats!
