This brush is designed to clean all areas of the nursing bottle. The large end will easily reach every corner and bend of the nursing bottle, while the small end is ideal for freeing residue from the nipple. A large multi-fan tip filled with a mixture of type 6.6 and 6.12 green and white nylon bristles helps liquid retention and scrubbing power.
The nipple end is type 6.6 white nylon.
