Boon Snug Straw Universal Silicone Straw Lids & Cup

My toddler used to knock over every cup within reach, but these silicone lids actually stay put on our regular cups. Cleaning is easy too since they're just silicone and nothing gets trapped underneath. No more puddles on the kitchen floor.

Even with my most rambunctious sippy-cup thrower, these lids pop onto whatever straw cup we have lying around and the seal holds tight enough that we've survived a full car ride with zero puddles. I love that I can finally buy any cup without worrying if the lid fits. The silicone is sturdy but flex

My toddler finally stopped turning every sippy cup into a fountain, and these lids fit on the cups we already own, which is half the battle. The silicone is soft enough that he chews on it without complaint, and I've washed them a dozen times without any warping or weird smells.
