Thermocups are designed by professional designers: they look elegant and are perfect for a variety of activities. Thanks to the 2 lids included, they are convenient for workouts, travel, and even beach parties. With the colored leak-proof Sapporo lid, it turns into a classic thermocup for tea or coffee, but if you replace it with a transparent one (with a straw!), you'll have a bright cocktail glass in your hands. Capacity is 532 ml. The double-walled construction with vacuum insulation keeps contents cold for up to 12 hours, hot for up to 6 hours (using the leak-proof lid). 2 lids included: one is 100% leak-proof with a locking mechanism for the drinking hole, the other has a hole for a straw. Does not contain BPA. Fits most car cup holders. Suitable for making cold drinks with ice, coffee, and tea. After filling with boiling water, let the liquid cool for 1-3 minutes. This will prevent deformation of the plastic lid components, which soften from high temperatures.
