0.5mm Mechanical Pencil Kit

The uni-ball 70137 Kuru Toga Elite is a refillable mechanical pencil designed for precise writing and drawing. Its 0.5mm nano diamond lead suits students, artists, and professionals who need consistently sharp lines for notes or detailed graphics. The silver barrel measures 1.3 by 7.1 by 19.1 centimeters and weighs .04 kilograms.

Rotating Lead Engine and Diamond Lead

The advanced rotating lead engine automatically turns the lead during writing to maintain a sharp point at all times. Extra durable diamond-infused lead is stronger than standard options, producing strikingly dark marks that resist breakage. A replaceable eraser allows quick corrections without smudging the page.

Refillable Design and Simple Maintenance

The pencil is fully refillable, so users can replenish lead and erasers without replacing the entire instrument. Installation involves inserting standard 0.5mm refills into the barrel, a process that takes seconds. Buyers who want a broader line width or a non-rotating mechanism should consider a different model.

Questions about this item

How often will the 0.5mm nano diamond lead need replacing?

The 0.5mm nano diamond lead is refillable and extra durable, lasting longer than standard lead; replace it when the barrel runs out.

What limits continuous writing with the rotating lead engine?

The rotating lead engine keeps the 0.5mm tip sharp during sustained use; the only limit is the finite lead supply inside the barrel.

Does the plastic barrel get warm or slippery during all-day use?

The silver plastic barrel measures 1.3 x 7.1 x 19.1 cm and weighs 0.04 kg, so it stays light and comfortable without heat build-up.
