Studio Oh! Coffee Tumbler

No, this tumbler is not dishwasher safe. We recommend hand washing it to preserve the integrity of the silicone coating and the glass construction.

This tumbler is not microwave safe. Please heat your beverage separately before pouring it into the tumbler.

The double-wall construction provides moderate temperature retention, keeping your coffee warm for a reasonable amount of time during a commute or while working at your desk. It is designed more for daily convenience than for long-term thermal storage like a vacuum-sealed flask.

The sip-through silicone lid provides a snug, secure fit for everyday use, but it is not completely leak-proof. It is designed to prevent splashes while you are drinking or walking, but it should not be tossed loosely into a bag.

The tumbler is crafted from borosilicate glass, which is known for being more durable and shatter-resistant than standard glass. While it is built to withstand daily use, it is still glass and should be handled with standard care.

The smooth-touch silicone coating serves two purposes: it provides a comfortable, non-slip grip that is easy to hold, and it adds a layer of protection to the glass exterior.
