A water brush has the same tip as a normal brush, but a body with a reservoir that you can fill up with water. There are many versions and sizes from different brands. You can use the water brush with watercolour, watercolour pencils or pens with water-based ink, just to give some examples. This is a very practical product that will let you create without any interruptions, since you do not have to dip the brush in water. When you push a button at the other end, the amount of water that you need will come out of the brush tip.
