The BrüMate Toddy is the world's first 100% leakproof, insulated portable coffee mug with a handle designed for your favorite hot, cold or carbonated drinks at home or on-the-go. Includes new BevLock Technology with a fully leak proof locking lid, so you can take your beverage wherever, whenever. The Toddy is your versatile, go-to mug, from toddies to coffee and everything in between. The TODDY XL lid takes around 5-6 uses to break in. During that break-in period you might notice that the lid is hard to twist on and off, to help speed that up just run the black gasket on the lid under water before putting the lid on.
