Bluepolar Tumbler

The lid is designed to be sealed for convenient carrying, which helps prevent splashes and spills during normal use. However, it is not fully watertight, so we recommend keeping it upright in your bag rather than tossing it in loose.

While the Bluepolar tumbler is primarily designed as a water glass cup for cold or room-temperature drinks, it is generally safe for warm liquids. Just be careful, as the material is not insulated like a traditional travel mug and will feel hot to the touch.

Yes, the lid features a dedicated opening that holds the included straw snugly in place. This ensures it stays upright while you drink and reduces the risk of it slipping out.

To maintain the clarity and integrity of the material over time, we recommend hand washing the tumbler and lid with mild soap. High-heat dishwasher cycles can cause clouding or warping.

The stemless base provides a low center of gravity, making it significantly more stable than stemmed glassware. It is less prone to tipping over on uneven surfaces, making it a reliable choice for casual settings.
