Expermenting withers the brand - Generals Chorcoal pencils. I really like these pencils the 4Bs and 6Bs are so soft and hug the paper really well. I used a thick watercolor paper, I have heard from Cesar Santos (amazing artist) that Fabriano Artístico hot press 300 g/m is the best for charcoal pencil. I could tell the quality was really good when I made my first few marks.
