High quality artists' grade colored pencils made by Sanford.
Their smooth, wax based leads allow intense colors and smooth blendings. Because of their outstanding characteristics, they are favored by many artists and designers.
And if you like the softness of Prismacolor Premier, but not the fact that the leads tend to break when you sharpen them - the trick is the right
sharpener, which does not bend and twist the soft waxy lead too much.
