Professional makeup brush, from the company Koopman,

How to use the brush:
The brush helps you build more coverage. It is ideal for makeup details and gives a more airbrushed result.

How to clean it:
Keep all the brushes together and wet only the bristles, being careful not to wet the handle and wood, with the "bristles" facing downwards.
Once the bristles of the brushes are well wet, place a small amount (drop) of special cleaner or mild shampoo on the bristles of each brush.
Create foam by gently rubbing each brush in your hand or using a special tool (glove), making sure that all the bristles are cleaned. You can also use your fingers for more detailed cleaning.
With the brushes facing downwards again, rinse the soap from the brushes with lukewarm water. Continue until all traces of soap are gone.
Dry the brushes on a towel. Never leave your brushes wet as moisture damages them.
