ZOKU's Luxe Ice Molds are made from BPA-free, durable silicone, ensuring easy release of large ice cubes. Slow-melting ice cubes keep cocktails chilled longer without diluting your drink! Impress guests with unique, textured ice cubes, adding a playful touch to any cocktail. Just fill the molds, freeze, and easily pop out the ice cubes with a push from the bottom.
