Sursip 40 oz Glass Tumbler for Adults - Reusable Iced Coffee Cup with Lid and Straw, BPA Free, Dishwasher Safe - White

Product Description

What type of cup is it, glass or plastic?
This product is a 40 oz borosilicate glass water tumbler. Unlike standard glass cups, borosilicate glass offers exceptional temperature resistance, so you don’t have to worry about it breaking when adding ice cubes to hot tea or iced boba tea/smoothies. Just add your ingredients and enjoy your beverage without concern.

Is the silicone sleeve removable?
Yes, the silicone sleeve can be detached. For easier removal and installation, it is recommended to do so when the sleeve is wet.

Why does the tumbler not sound like glass when tapped?
The outer silicone sleeve insulates the glass, which is why it does not produce the typical sound associated with glass. To hear the glass sound, simply remove the silicone sleeve and tap the glass itself. You can also test it by lighting the tumbler to confirm it is indeed made of glass.

Is this cup sweat-proof due to the silicone sleeve?
Currently, no glass can be completely sweat-proof when exposed to varying temperatures. However, borosilicate glass performs exceptionally well with temperature changes and will not shatter when transitioning between -20℃ cold and 130℃ hot.

If your glass tumbler arrives damaged due to shipping, please contact us via Amazon, and we will promptly send you a replacement.
