Features:*Quick Freezing Technology - Turn your favorite drinks like cola and juice into refreshing slushies in just seconds. Just store it in the refrigerator before use (adjusting the cup insert to the right temperature). The soft silicone cup allows you to transfer cold air directly into your drink. * Refreshing and Easy to Use - The design makes it easy to enjoy satisfying smoothies. The removable dome lid helps prevent spills, and the reusable spoon gives you the option to tip over or clean up for refreshing meals. * Undiluted deliciousness - Most homemade slurries use a mixture of ice and juice to achieve a semi-frozen consistency, which can cause the original flavor to be diluted. It doesn't require ice, instead using the freezer lining as a cold source. The result is a pure, sugared version of your favorite drink that tastes exactly like the original. *Customize your cool flavor, don't buy the limited slushy flavors at the ice cream shop. Use it to customize your own cold drinks. You can dunk it in sparkling water, freeze cappuccino, or make iced iced tea. Add to almost any ice-cold beverage, give it a quick massage, and enjoy a new version of your favorite drink. *Reusable for endless fun - Reusable and dishwasher safe. It allows you to try new flavors every day or every hour. Simply wash the cups and refreeze them to start your next freezing adventure. SAFE AND NON-TOXIC - All parts are non-toxic, food-grade and BPA-free, so the only thing you have to worry about is the dreaded brain freeze.
