How to judge the quality of the towel rack coating:

1. Look: Generally speaking, the brighter and finer the surface, the more obvious the mirror effect, and the better the plating process

3. Grip: You can use the grip method to see if the material is good or bad. Some merchants will use cast iron material to pretend to be full copper or copper-zinc alloy hardware.
