This Straw and Sippy Cup Cleaning Brush Set from OXO Tot makes it easy and convenient to keep your sippy cups clean. Carefully designed brushes reach in and around bottlenecks, straws, and other hard-to-reach places for a deep-down squeaky clean. The bottle brush bristles minimize water spray while you wash, the straw brush cleans out every type of straw, and the detail brush gets into crevices and small spaces in lids. Each brush has non-scratch bristles tough enough for serious scrubbing (without scratching) and soft, non-slip handles for a secure grip – even when wet.
