Holbein
ARTISTS' COLORED PENCILS OP920 24-color set

The soft core makes it easy to spread.
The soft core allows you to use a thicker core for even, sticky application, or a thinner core for smooth, fine line drawing as desired.
Excellent lightfastness
High-grade pigments are carefully selected to minimize fading and discoloration caused by light.
Easy to Draw with Thick Lead and Thick Shaft
The core is 3.8 mm in diameter and thick enough to fill a large area at a time. The 7.8mm-diameter barrel is easy to hold and does not tire the hand.
Can paint over watercolors, gouache, and acrylics.
The paint sticks well to any paper and can be used with watercolors and acrylics.
Can be painted in a watercolor style with Merz.
If you draw on the screen with colored pencils in advance and then dissolve and blur the surface with "Merz", you can create a watercolor-like finish.
