Write crisp, bold lines without compromising cleanliness—uni’s advanced smudge-resistant lead delivers sharp, dark results while keeping your notebook pristine. With a sleek slide-case and cutting-edge Smudge-Proof formulation, it’s made for those who write often and revisit their notes.

Key Features

• Smudge-Proof Technology: Proprietary formulation keeps lead particles tightly bonded to the page, reducing smearing from hand contact or paper friction by up to 50% under specified conditions.

• Bold & Clean Writing: Creates dark, defined lines while minimizing mess—ideal for long-term note-taking and studying.

• Marker-Friendly: Resists feathering and bleeding even under highlighter ink; prevents marker tips from picking up lead residue.
