LOOK SHARP! , Boon's CACTI makes cleaning easier and looks cute while doing it! This fully stocked set includes four cacti in different sizes, but you'll never need to worry about pricks. The only bristles on these brushes are made out of durable nylon which is great for getting the goop out of bottles, straws, sippy cups and breast pump parts. The vase drains water and keeps the brushes together so that it's easy to grab exactly the right one for the job. This cute collection lets you scrub to your heart's content.
