CRETACOLOR NEGRO-PENCILS (ZULU PENCILS)

The addition of wax to the leads of these pencils produces a particularly soft stroke and exceptionally dark black. They can only be partially smudged and they cannot be turned into paint. Erasing is also limited. Their effect depends greatly on the paper surface. The hard qualities allow very subtle drawing effects and fine lines as well as fine gradations in grey. Overall Ø is 8.5mm, length is 170mm. Price per pencil.
