Boon Cacti Bottle Cleaning Brush Set contains bottle brush, straw brush, nipple brush, and a detail brush which make cleaning easier with a gentle touch while doing it. This fully stocked brush set includes four cacti designed brushes in different sizes, but you may never need to worry about pricks. The only bristles on these cleaning brushes are made out of durable nylon which is great for getting the goop out of baby 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. While the purpose of the needles on these durable nylon brushes is to get the stickiness out of bottles, sippy cups, and breast pump parts, it's great. This cute cactus vase design replacement brush set gives you the cleaning you crave to your heart's content. Boon is a leading innovator, designer and manufacturer of infant and baby products.
