Carry your coffee in a cup you actually want to hold. This reusable glass cup feels good in your hand, keeps your drink at the right temperature, and travels beautifully because the cork band protects the glass.
- Tempered glass body with real cork band for natural grip and warmth
- Splashproof press-fit lid with optimal mouthpiece for drinking comfort
- 25% recycled glass and 100% recovered cork band
- Includes silicone gasket and reusable lid
- Lightweight and fits standard car cup holders
- Alder colour with warm, natural aesthetic
The experience of drinking from this cup is different from plastic. The glass transfers temperature gently to your lips rather than shocking them. The cork band is warm to hold and feels substantial in your hand. These small details add up to something you want to use again and again rather than something you tolerate because it is sustainable.
KeepCup has refined this design over years of use. The splashproof lid is press-fit, which means you do not fiddle with screwing mechanisms. The mouthpiece is designed so your nose sits comfortably and the aroma of your coffee reaches you as you drink. This is a detail that seems minor until you use a coffee cup with a poorly designed lip, then you realise how much it matters.
The cork band serves both function and aesthetics. Functionally, it protects the glass from breaking if you knock the cup against something, and it prevents burns if the glass gets hot. Aesthetically, cork is natural and warm in a way plastic is not. It looks like something someone cared about designing.
The glass is tempered, which means it is much stronger than regular glass and will not shatter into dangerous shards if you accidentally drop it. It is still breakable, unlike plastic, but realistic impact will not destroy it. This is a trade-off you make for the experience of drinking from actual glass.
The 25% recycled glass means KeepCup is not mining virgin material just for coffee cups. The 100% recovered cork band comes from wine bottle cork waste, so you are using material that would otherwise end up in landfill. This is the kind of circular design that matters.
KeepCup donates 1% of all revenue to environmental protection organisations, and they hand-assemble products in their warehouses, keeping jobs local rather than maximising offshore manufacturing efficiency. These decisions are visible in how the cup is made and how it feels.
The Alder colour is a deep burgundy that looks good in any environment. Whether you are in a corporate office or a hipster café, this cup looks intentional rather than like a promotional giveaway.
This is the cup you reach for in the morning before you have thought about it. It becomes part of your routine so completely that drinking from anything else feels wrong.
How to Use
- Remove the lid from the cup.
- Fill with your hot or cold drink to just below the rim (not to the very top, as this helps prevent spillage).
- Place the lid on the cup firmly until it sits flush. You should hear a small click.
- Drink as normal.
- To clean, remove the gasket. Rinse the cup with warm water.
- Wash the lid separately by hand or in the dishwasher.
Product Care
Hand wash the glass cup body with warm soapy water to preserve the cork band and prevent damage. The lid (without the gasket) is dishwasher safe. The silicone gasket should be hand washed. Do not microwave. The cork band should not be soaked. A soft damp cloth is sufficient for cleaning the cork.

What These Do
- Tempered glass - Chemically treated to be much stronger than regular glass, resistant to thermal shock from hot and cold drinks, and safer if accidentally dropped.

- Tritan Renew plastic - Food-safe, BPA-free, and made with 50% recycled content. Used only for the lid to keep the cup functional.
- Silicone gasket - Creates a watertight seal between the lid and cup, preventing spillage while remaining flexible and durable.
