Gelas Kaca

The double-wall design is genius—my coffee stays hot without the cup ever burning my fingers, and it looks sleek on my desk. I've been using it daily for a week and the borosilicate glass feels sturdy, not delicate. Pairs perfectly with the Sip Lid for commuting.

I was skeptical about the double-wall glass really keeping my drink hot, but after an hour my tea was still steaming. The borosilicate glass feels sturdy and the sip lid clicks on securely enough that I've tossed it in my bag without any leaks.
