Dr. Brown's 細型透氣孔清潔刷 4入

I was skeptical about cleaning the tiny vent parts, but these four brushes fit perfectly and make the whole process much faster. The bristles are stiff enough to really scrub the narrow tubes without bending out of shape.

These tiny brushes are perfect for getting into the vent straw of the bottle, something I could never clean properly before. They're thin enough to bend around the corners but still feel sturdy after several washes.

I was skeptical at first, but these little brushes actually reach every nook in the vent system that the regular sponge misses. They've made cleaning the internal parts so much faster during the nightly bottle wash routine.
