A new Era of straw tumbler is here. Our Era tumbler is totally leakproof, and聽made for stress free sips on the go.

Era Tumblers are 100% leakproof with cold beverages and iced carbonated beverages when in the locked position. A 50% ice to liquid ratio is recommended when using carbonated beverages.

Not recommended to be used in the locked position with hot beverages. Using hot beverages with a straw poses a scalding risk.
