Handcrafted by artisans in the United States, PRIMO Euro Blend Compressed Charcoal Sticks were created especially for artists seeking an intense, creamy, smooth charcoal. They can be used alone or in combination with other charcoal, pastel or mixed media. They can create broad strokes or can be sharpened to create desired or fine lines to achieve artists’ desired effects. They are also great for quick layouts for oil painting. This set includes three black (HB, B, and 3B) and one white charcoal stick.
