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.

Smooth-Writing & Erasable Colored Mechanical Pencil Lead
This colored lead writes smoothly and can be cleanly erased with a standard eraser?just like regular graphite lead.
Despite being colored, it offers the same level of erasability as typical graphite mechanical pencil leads, allowing you to write, erase, and rewrite as needed.
Perfect for repetitive study methods such as writing incorrect answers in red and erasing them once learned.
