Beautifully designed, durable, lightweight and taste-neutral glass travel mug

People are passionate about ensuring the flavour of their tea or coffee remains authentic, and glass is completely taste-neutral. This stunning travel mug allows you to take your drink with you on-the-go, without fear of it leaking, and ensuring the flavour stays as you intended.

black+blum spent many years on the development and the design of this product, and what they have created is authentic and functional, it’s made to last a lifetime.

Fully Leak Proof & Easy Clean - This is the first fully leak proof glass travel cup on the market. The unique lid design easily dismantles (and reassembles) for quick and thorough cleaning - all the parts are also dishwasher safe.

Protective & Non-Slip Sleeve - The silicone sleeve helps protect both the inner glass from breaking, and your hands from the heated contents of the Travel Cup. It makes it much easier to grip and is also non-slip on a table surface.

Taste-Neutral & Comfort Drinking - The hand-blown borosilicate glass is completely flavour-neutral and ensures your drink tastes as you intended. The glass cup has a smooth rim, and has been designed to drink with or without the lid.

Lockable Easy Open Lid - The lid is lockable (so no danger of it opening in your bag) and can be opened or closed simply with one hand, making multi-tasking a dream.

More Controlled Drinking - The spout enables ‘direct flow’ which, similar to drinking from a mug, means you’re less likely to burn yourself. This feature is not common among most leak proof travel cups.
