Uni Pencil Leads in Metal Case 0.5 mm HB (40 pc.)

The Uni pencil leads UL-SM-0.5 HB come in a compact metal tin from Japan and offer 40 replacement leads with a 0.5 mm core diameter in HB hardness. The graphite mixture is specifically designed for smudge resistance – a noticeable difference when drawing and writing on paper that gets a lot of hand contact. Add to that a remarkably durable tip: the leads maintain their sharpness longer than standard replacement leads, allowing for precise work over extended distances.

Features

• Smudge-resistant graphite formula – lines and sketches remain clean, even when your hand glides across the surface or pages are pressed together.
• Longer-lasting point – the tip breaks less frequently and stays fine, which is a real advantage especially for technical drawings, tight lettering or clean hand lettering.
• 0.5 mm / HB – the most popular combination for writing and drawing: precise enough for detail, soft enough for flowing lines without excessive pressure.
• Metal tin – protects the leads from breaking in your pocket or pencil case, easy to open and dispense, takes up minimal space.
• 60 mm lead length – compatible with standard mechanical pencils with 0.5 mm guidance.
• 40 pieces per pack – a supply that lasts a long time, even with intensive daily use.

Use & Tips

• Technical drawing and construction sketches: the smudge-resistant, durable tip produces clearly legible lines on graph paper or smooth drawing card.
• Hand lettering and calligraphy with pencil: HB is soft enough to show pressure variations – smudge resistance prevents guide lines from smudging when you refine your work.
• Bullet journaling and planning: sketching layouts, grids and graphics that are later inked over – smudge-resistant leads leave fewer graphite traces beneath the ink.
• School supplies and exams: HB is the international standard for exam papers that are machine-read; the long-lasting point reduces interruptions.
• Storage: store the metal tin upright or on its side – thanks to the robust case, you can also carry the leads loose in a pencil case without breaking them.

For Drawing Enthusiasts

The smudge resistance of these leads is no accidental feature, but rather the result of the graphite-binder composition developed and manufactured by Mitsubishi Uni in Japan. While many standard leads leave streaks on the paper surface when smudged or erased, here the line remains cohesive and can be erased cleanly without dirtying the paper fibres. Those working on calendered, smooth papers benefit particularly: the graphite particles sit closer to the surface, further enhancing the smudge-resistant effect.
