Enjoy the look and clean taste of glass. KeepCup Longplay Cold Cup with Boba Straw is made from high-quality tempered glass with a removable protective sleeve.

Is tempered glass better than plastic for iced coffee cups?

Tempered glass offers a premium café feel with a clear, clean finish that doesn’t hold flavour or odour. It’s heavier than plastic but feels elevated — ideal for those who love the ritual of a perfect iced coffee.

Does tempered glass crack with cold drinks?

Tempered glass is designed to handle temperature changes, so it won’t crack with cold drinks or ice. KeepCup’s glass is heat- and cold-resistant — safe, strong, and made for daily use.

Are glass coffee cups good for iced coffee?

Absolutely. KeepCup’s Tempered Glass Cold Cup is crafted from toughened soda-lime glass that’s strong, clear, and made to handle both hot and cold drinks. It shows off your coffee layers beautifully while keeping taste pure and fresh.

Can I pour hot drinks in my Cold Cup too?

You can, but the Cold Cup Longplay really shines with iced drinks like oat lattes, matcha, and cold brew. It’s designed for chill moments — if you’re after something for your flat white or long black or a delicious hot tea, swap to our press fit sipper lid or clear tritan lid.
