Zojirushi SX-FSE45AJ Tumbler

Thanks to Zojirushi's vacuum insulation technology, this tumbler is designed to maintain beverage temperatures for several hours. While exact times depend on the starting temperature and how often you open the lid, it is highly effective for keeping coffee hot during a morning commute or iced drinks cold throughout the workday.

Yes, the included tea strainer is versatile and works well with loose-leaf teas or tea bags. It is designed to keep leaves contained while you drink, making it a convenient feature if you prefer brewing directly in your tumbler.

To preserve the vacuum seal and the exterior finish, we recommend hand-washing the tumbler with mild dish soap. While the stainless steel construction is durable, high-heat dishwashers can potentially damage the insulation properties over time.

No, the vacuum insulation prevents condensation from forming on the outside of the tumbler. You can place it on your desk or in your bag without worrying about water rings or moisture buildup.

This tumbler is designed for portability, but it is not intended to be tossed loosely into a bag like a fully sealed travel mug. While the lid is secure, it is best kept upright to prevent any potential spills.
