This bottle brush set offers practical cleaning performance for bottles, cups, bowls, and other narrow or deep containers. Designed for regular use, the brush combines firm nylon bristles with a flexible head and a textured plastic handle to reach tight corners and bottoms with ease.

Improved handling: Plastic handle with convex thread provides a secure grip and better control when twisting or pushing the brush into narrow necks. Portable and practical: Compact design works well at home or on the go for routine cleaning tasks. Materials and performance Bristles: Nylon fiber for durable, effective scrubbing.
