Our 2-in-1 brush is America's favorite. We have the #1 selling bottle and nipple brush because of our unique design and quality. Our bottle brush has soft bristles and a strong sponge tip for scrubbing hard-to-clean places. And the nipple brush is conveniently stored in the handle so you never have to look far for your favorite little brush. Non-slip handle makes it easy to hold when wet. Nylon bristles are durable yet soft.
