Fruit-Themed Double-Walled Gel Freezer Tumblers with Straws

These vibrant, 550ml travel cups are specifically designed for keeping beverages ice-cold using a specialized non-toxic cooling gel layer between the double walls. To use, the tumblers are typically placed in the freezer upside-down for a few hours until the gel freezes into a "cracked ice" appearance, providing long-lasting thermal insulation without diluting the drink. The exterior is decorated with minimalist fruit seed patterns to represent watermelon, pitaya (dragon fruit), and lemon, while the matching screw-on lids feature a flip-top straw port for spill-resistant sipping. Constructed from durable, BPA-free acrylic, these tumblers are a fun and functional accessory for enjoying smoothies, iced coffees, or chilled juices on the go.
