This versatile nylon-tipped brush pen from Pentel allows you to fill the barrel with any water-soluble medium (water-soluble inks, watercolours or gouache) to use for lettering or painting. Alternatively, you can just use water and pick up watercolour or gouache colour from your palette to create high wash effects.
You can control the density of colour by squeezing on the barrel of the Pentel brush pen to make the brush wetter or drier. It's also an ideal companion for the watercolour pencil artist. Using a water filled barrel you can create imaginative blends and washes with your watercolour pencils. The Pentel Aquash water brush comes in three nib sizes: Fine, medium and broad.
