Boons CACTI makes cleaning easier and looks cute while doing it. This fully stocked set includes four cacti in different sizes, but youll never need to worry about needles. The only bristles on these brushes are made out of durable nylon which is great for getting the goop out of bottles, sippy cups and breast pump parts. The vase drains water and keeps the brushes together so that its easy to grab exactly the right one for the job.
