I have a template on the handle of aluminum alloy, but this brush head is also metal. First, the taste is very uncomfortable. If the weather is colder, don't you freeze your mouth? Secondly, how does the aluminum alloy brush head vibrate? Is it another product with the light handle shaking hemp and the bristles motionless?

Did you see the brush head or the traditional plastic brush head at the exhibition yesterday?

Aluminum alloy is really rare, the cost is estimated to be high, and the hair looks a bit fake.

The shape is quite good, portable and easy to buy is not reflected.

What does aluminum alloy integral molding mean? Does it mean the handle integration of the brush?

There are many lines than usual.
