Key Features

  • Uni NanoDia Color Mechanical Pencil Leads, 0.5mm 7 Color MIX

  • 5 Pack/total 100 Leads Value Set

Why choose this product

Authentic Japanese Engineering for Superior Writing

Uni NanoDia leads are renowned for their advanced graphite composition, offering a smoother writing feel and enhanced break resistance compared to many standard leads. This imported set ensures you receive the genuine Japanese-engineered product, known for its consistent quality and vibrant, fade-resistant colors. The 0.5mm fine point delivers precision for detailed work, making them ideal for students and professionals who demand reliability and performance in their writing tools.

Ideal for Students & Artists, Consider Alternatives for Heavy-Duty Drafting

These leads are perfect for everyday note-taking, journaling, creative sketching, and color-coding study materials. The vibrant colors add a fun element to writing. However, for extremely heavy-duty technical drafting requiring a specific lead hardness (like 2H or 4H) or a thicker lead size, exploring specialized drafting leads might be more suitable. This set is designed for general writing and artistic use.

How to use

  • Load the Mechanical Pencil — Ensure your mechanical pencil is compatible with 0.5mm lead size. Open the pencil's lead reservoir, typically located in the barrel or at the top near the eraser. Gently insert one or two leads at a time.
  • Advance the Lead — Click the pencil's mechanism (usually the top button) to advance the lead until a small portion is exposed. Avoid advancing too much lead at once to prevent breakage.
  • Write or Draw — Begin writing or drawing with your chosen color. The NanoDia leads offer a smooth, consistent line. If the lead breaks, simply click the mechanism again to advance more.
