Black+Blum Charcoal Water Filter Hydration with Locking Coil, Old Japanese Tradition, Lasts 6 Months, Natural Wood

EASY CLEAN & 100% LEAK PROOF: The lid is completely leak proof and has been designed so that it is easy to dismantle/reassemble and thoroughly clean all parts - they are also all dishwasher safe. LOCKABLE & ONE-HANDED LID: Our lid can be held and opened or closed with one hand, making it easy to multitask while on-the-go. The lid is also lockable so there is no danger of it opening in your bag. DIRECT FLOW DRINKING: We designed the spout of our Travel Cup to replicate drinking from a mug or a cup - so you’re more in control and less likely to burn yourself. We’ve called this feature ‘direct flow,’ and it gives you a better drinking experience. SMOOTH EDGE DRINKING: We wanted to design a Travel Cup that would be enjoyable to drink from with or without the lid, a feature which had not often been considered by other products on the market.
