Caran d'Ache Museum Aquarelle Waterbrush Pen - Medium Brush
The Caran d'Ache Museum Aquarelle Waterbrushes are perfect for use in the studio or sketching on-the-go. Each waterbrush has its own basin which can be filled with water to enhance the properties of fountain pen ink sketches, watercolor pencils, or crayons. These brush pens are ideal for transporting, and the pump system makes it easy to clean out the brush tip with water. This blue-accented brush pen has a medium nib that is more ideal for producing detailed sketches, calligraphy, and illustrations.
To fill this brush pen:
1) Unscrew the brush tip/grip of the pen, dip the barrel in water, and pull back on the piston.
2) Reattached the brush tip/grip.
3) Turn the barrel right side up so that the brush tip is facing up, and the piston pointing down.
4) Push the piston slowly back into the pen.
For max capacity, you can push the excess air out of the barrel after filling the first time, then fill again.
