The travel cup from Black+Blum retains the authentic taste of tea and coffee. Glass is completely tasteless. With this design, Black+Blum wanted to give people the freedom to take their drinks anywhere without the fear of spills and be assured that the taste is retained as intended.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. The unique lid design easily dismantles (and reassembles) for quick and thorough cleaning - all the parts are also dishwasher safe. 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. 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.- BPA-vrij- 100% leak proof- Lockable- One handed opening and closing- Non-slip, easy grip, protective silicone sleeve- Hand blown durable and lightweight borosilicate glass- Fits in bike bottle cages and car cup holders- Dishwasher safe and lid disassembles easily for thorough cleaning
