Soft high elasticity bristles
Soft Q-elastic bristles go deep into the bottom of the bottle and can be cleaned freely at 360 degrees.
360 rotatable brush handle
The turning brush handle does not take much effort to clean the bottle.

Liquid Silico Rubber is a kind of non-toxic, heat resistant, high-resilience, flexible thermosetting material. Besides, non-reactive, elongation, tear strength, resistant to extreme environments are LSR's advantages.
Liquid Silicon Rubber's vulcanization behaviors: Low viscosity, fast curing, shear thinning and higher thermal expansion coefficient.
