Triangular barrels eliminate the constant micro-adjustments your hand makes gripping round pencils. Koh-I-Noor designed these Triograph pencils with three flat sides that naturally align with thumb, index, and middle finger, reducing fatigue during extended drawing sessions. The ergonomic benefit becomes most apparent after an hour of continuous work, your hand simply stays more relaxed.

That 10.5mm core is genuinely oversized, nearly double the diameter of standard pencils. This thick graphite delivers broad, velvety strokes ideal for tonal work, quick gesture studies, and blocking in values across large areas. You can lay down significant coverage quickly, then refine edges and details with the sharpened point. The artist-grade graphite maintains smooth consistency without the gritty scratch that cheaper leads produce.

Stained cedar casings sharpen cleanly in any large-hole sharpener without splintering or crumbling. Available in 2B, 4B, and 6B grades, soft enough for rich darks and expressive mark-making, yet controllable for more deliberate work. Sold individually so you can stock up on the specific grade you use most, or order six for a complete box spanning the range.
