Is borosilicate glass safe for hot coffee?

Yes. Borosilicate is made to take temperature swings, so hot coffee or tea is far less likely to crack it than ordinary soda-lime glass. Avoid pouring boiling liquid into a cold cup straight from the fridge.

How much does it hold?

About 11.8 fl oz, roughly a standard mug plus a little. That suits a coffee or juice serving, not a full day of water.

Can I put it in the dishwasher or microwave?

The glass itself is generally microwave and dishwasher safe. Wash the lid and straw by hand to keep them from warping or clouding.

Does it keep drinks hot or cold?

No. It is single-wall glass with no vacuum layer, so it insulates about as well as a mug. It is for drinking soon, not for carrying a drink for hours.

Is it good for travel?

Only lightly. The lid helps against splashes, but glass is heavy and breakable in a bag, and 12 oz is small. A stainless tumbler suits commuting better.

What comes in the box?

The glass tumbler, a lid and a straw. Check the listing for the exact lid and straw style before ordering.

Our take on the Thheic Glass Tumbler with Straw and Lid Ribbed Borosilicate Drinking Cup

The Thheic is a ribbed borosilicate glass tumbler with a straw and a lid, sized at about 12 fl oz. Borosilicate glass handles hot coffee and cold juice without the thermal shock that cracks ordinary glass, and the ribbed wall gives it grip and a look that stands out from plain smooth tumblers. At roughly 12 oz it is a desk or bedside cup rather than a commuter bottle, and the glass body is heavier and more breakable than the stainless and plastic tumblers it competes with.
