6" 12 stick packs - These charcoal sticks contain no binding agents, so erase easily. They are more delicate than compressed charcoal and susceptible to breakage if not handled gently. They are soft and powdery, they are less suited for fine detail work. Willow and Vine charcoal are less dense then compressed charcoal and produce a lighter, warmer tone.

Vine charcoal is almost the same as Willow charcoal except they are produced from different materials burnt to a degree of precise hardness for drawing

Vine Charcoal is made of grape vines

Willow Charcoal is made from the twigs of willow trees
