By far the best wooden pencil for sketching in the world! It's not just my personal opinion, it's well-known among artists, that's why they sell it in packs of 12!!! In short.. The quality, especially in how the material works and how flawless the pigment is, is literally unmatched!!! It's hard and you don't feel any oil or wax in the sensation. Because of this recipe, the pencil can deliver the softest tone and with a few more strokes or a little more pressure, it can deliver the darkest and deepest Red Chalk performance! Another very important thing is that it's the only pencil on the market that actually has the color Red Chalk or otherwise known as Sanguine as other companies call it. If you use the right paper, you will fall in love with the result! It's suitable for all types of sketches, whether it's portrait, landscapes, or even Urban sketching! Koh-I-Noor also makes it in 5.6mm, but for some reason, they change its name again and call it Russet Sepia! It's my favorite sketching pencil, for even more flexibility in performance, I use it in 5.6mm and the best sketching pencil is the Koh-I-Noor 5340.
