Glass Reusable Coffee Cups & Tumblers

From the world’s original reuse pioneers, KeepCup’s glass range combines premium materials, clean lines, and daily practicality. Every cup replaces hundreds of single-use cups — proof that small steps make a big difference.

With splashproof lids and sleek, barista-standard design, these cups are as practical as they are beautiful. Whether you choose the timeless Brew Cork or the classic Brew Glass, you’ll taste coffee the way it was meant to be — pure, balanced, and waste-free.

Choose your finish — cork or silicone — and your favourite lid style. Then make your coffee, your way. Because when sustainability looks and feels this good, reuse becomes second nature.

Glass retains heat well for shorter coffee styles like flat whites and cappuccinos. For longer-lasting warmth, choose the KeepCup Longplay with a double-wall design that insulates without adding bulk.

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.

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.

Both offer a secure grip and heat protection. The natural cork band is sourced sustainably and adds a soft, organic feel, while the silicone band is lightweight, flexible, and dishwasher safe. Choose cork for a warm, tactile experience or silicone for easy cleaning — either way, it’s reuse done right.

The Cork band has more thermal insulation and a wider grip so we offer with 16oz/450ml glass. We only offer the silicone band in 12oz size with a glass base.

Yes. KeepCup glass cups are made from heat-resistant toughened glass designed to handle both hot and cold drinks, and the cork or silicone band protects your hands while keeping the warmth in the coffee.

On how long it stays hot: glass holds heat well for shorter coffee styles like flat whites, cappuccinos and piccolos — the drinks it was designed around. For longer-lasting warmth, the Longplay adds a double wall and a removable sleeve, insulating without much extra bulk.

Avoid thermal shock: do not take glass from the freezer to boiling water, or the reverse.

The KeepCup Brew Cork and Brew Glass ranges are made from durable tempered glass and come with splashproof, press-fit lids that make drinking easy on the move. Designed for coffee purists who want clarity, quality, and comfort, they’re barista-standard and made to last.
