[Online Exclusive] Stainless steel tumbler featuring an eye-catching coffee bean package design

This tumbler features a design inspired by the packaging of Starbucks' "Sumatra" core coffee blend. It showcases the Sumatran tiger—native to the island of Sumatra—along with the Siren logo at the base. It is equipped with an easy-to-use sliding lid, and the wide opening makes it simple to pour in drinks, add ice, and clean. The vacuum-insulated, double-walled stainless steel construction offers excellent heat and cold retention.

Not microwave or dishwasher safe.
The lid is not completely leak-proof. Please handle with care to prevent the lid from coming off and causing spills.
