The answer to your spill proof problems! I love my other cups but needed to step it up to something that doesn’t leak with knocked over by babies and toddlers! My bff gifted me a @brumate tumbler and it’s a game changer! Lid easily twist on and off, straw fits sing inside and with the twist of the lid you can place it in a leak proof setting! Best pool and beach cup! Makes a great gift! #LTKGiftGuide
