Compared to our previous color mechanical pencil leads, this lead features approximately 40% stronger tip durability, making it significantly more break-resistant.
It also offers erasability equivalent to sumi-style leads, allowing you to erase and rewrite with ease.
Each lead contains about 400 million nano-diamonds embedded in the core structure, delivering a dark and exceptionally smooth writing experience.

A durable, long-lasting 2.0mm lead that resists breaking and wearing down easily.
Writes well on a variety of surfaces including wood, concrete, and stainless steel.
Recommended use: For marking on wood, concrete, and other tough materials.
Ultra-Strong Lead with Bold and Smooth Writing
The secret behind the smooth, dark lines of uni's Nano-Diamond lead lies in its low-friction design?achieved by uniformly aligning high-density graphite particles. By evenly dispersing nano-diamonds between the graphite particles, internal friction is reduced, resulting in an exceptionally smooth writing experience.
Each lead contains approximately 400 million nano-diamonds.
The case features a two-step sliding lid that allows you to control how many leads you dispense at a time.
