Mechanical Pencil Rotring 2164109 3 pcs Silver

The Rotring 2164109 mechanical pencil set contains three silver-finished mechanical pencils designed for precise writing and technical drawing. Each pencil has a metal body made of durable brass, a 0.5 mm lead diameter for fine lines, and comes in three writing colours: black, blue and red. At approximately 32 g per set, the pencils are lightweight and balanced for steady control during extended use.

Advantages

The brass construction provides increased durability and a solid, balanced feel while remaining relatively lightweight. The 0.5 mm lead diameter offers consistent, fine lines suitable for detailed work. Having three pencils with different ink colours included allows quick colour distinction in notes and diagrams. Slim silver finish gives a professional appearance suitable for office, studio, and classroom environments.

How to use

Advance the 0.5 mm lead by clicking the push-button mechanism as needed; use short clicks to avoid excessive lead protrusion and breakage. Replace lead refills with 0.5 mm graphite leads compatible with mechanical pencils. For colour changes, use the pencil assigned to each colour to keep writing consistent. Store the pencils capped or with lead retracted to protect the tip when not in use.

Recommendations

Use the 0.5 mm lead for precise line work and switch to a softer or harder grade of lead depending on whether darker lines or greater abrasion resistance are required. Clean the tip periodically if debris accumulates, and avoid dropping the pencil to preserve tip alignment and mechanism function.
