Can I put my reusable glass coffee cup in the dishwasher?

The glass and silicone components are dishwasher safe (top rack only). If your cup has a cork band, handwash it gently to protect its shape and finish. Designed for daily use, each KeepCup glass cup is easy to clean and even easier to love.

Is the lid on a KeepCup glass coffee cup leakproof?

KeepCup lids are splashproof, not fully leakproof — perfect for sipping on the go, not for tossing in a bag. The press-fit design with sipper plug prevents spills while giving you that café-style drinking feel.

Are reusable glass coffee cups safe for hot drinks?

Yes — KeepCup glass cups are made from heat-resistant, toughened soda-lime glass that’s designed to handle both hot and cold drinks. Paired with a cork or silicone band, they protect your hands while keeping the warmth where it belongs — in your coffee.
