FULLY LEAK PROOF + EASY CLEAN - The glass travel cup is uniquely designed to eliminate spills and leaks. The travel mug’s lid easily dismantles (and reassembles) for quick and thorough cleaning - all the parts are also dishwasher safe PROTECTIVE + NON-SLIP SLEEVE - The non-slip sleeve makes it easier to grip the cup while protecting the inner glass from breaking and your hands from the heated contents of the travel cup TASTE-NEUTRAL + COMFORT DRINKING - Made from completely flavour-neutral hand-blown borosilicate glass to ensure your drink tastes as you intended. The glass cup has a smooth rim and has been designed to be used with or without the lid LOCKABLE EASY OPEN LID - The lid is lockable (so no danger of it opening in your bag). It can be opened or closed simply with one hand, making it perfect for multitasking - while driving, biking or working 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
