Our Travel Tumbler is 100% leakproof, so you don’t have to worry while you are on the go; in any case, we recommend not to overfill it.
Avoid shaking Travel Tumbler, especially when using it with boiling-hot beverages drinks, as it may cause excessive pressure.
Keep away from kids when using Travel Tumbler with boiling-hot beverages.
In addition, the Tumbler Sport Lid with straw is not designed for hot or boiling drinks, as this accessory is intended for hydration with minerals, electrolytes, cold or lukewarm drinks of any kind, but not boiling ones. In fact, sipping a boiling drink with a straw (although silicone is resistant to high temperatures) can be dangerous and the internal pressure of the boiling liquid can compromise the hermetic seal of the product.
Not intended for use with carbonated water.
