Unique paint brush with water compartment on Aliexpress. A real find for all artists and just lovers of painting!) Brush comes unassembled. To reassemble it is easy. You just need to screw it up. Just remember to screw it backwards. The quality is fine, no water leaks. The brush is plastic. It is very resistant. The top part is easy to hold. The brush fits comfortably in the hand. The hair is synthetic. Soft. Holds its shape well and for a long time. The water does not come out just like that. A little pressure and a drop of water appears. And you know how amazing it was when my hand was looking for a cup to wash and get water on the brush…-) Best price and great reviews. The most interesting and unusual stationery in a huge selection on the official website of Aliexpress.
