The Koi brush pens have a very nice grip and a nice soft brush tip. You make thin, medium and thicker strokes with these brush pens. The pen tip quickly returns to its normal shape. It is easy to blend with these pens, because the ink of the Koi Brushes is water based. The brush pens are odorless. Good to combine with the watercolor brushes from Pentel.
The Koi Brush pens are available in sets of 12, 24 and 48.
