Gel Pen Lean model 21739 — 0.5 mm tip, blue ink, 15 cm, brown cat paw grip

Lean gel pen model 21739 is a 15 cm writing instrument with a 0.5 mm fine metal tip and blue gel ink. The pen combines a slim plastic body with a brown cat paw–shaped grip that supports ergonomic hold and provides a decorative accent. The 0.5 mm tip delivers precise, consistent lines suitable for detailed handwriting and everyday notes, while the gel ink offers smooth flow and clear blue color on standard paper.

Advantages

The fine 0.5 mm metal tip enables accurate, thin lines for legible handwriting and detailed annotations. Gel ink provides smooth, skip-resistant writing and quick color saturation. The brown cat paw grip improves fingertip comfort and stabilizes the hand during extended writing sessions, and the compact 15 cm length makes the pen easy to carry in pencil cases or pockets. The overall design balances function and a playful aesthetic without adding bulk.

How to use

Remove the cap and hold the pen so the cat paw grip rests comfortably between the thumb and forefinger. Apply gentle, consistent pressure while writing to allow the gel ink to flow evenly; heavy pressure is not required and may shorten tip life. Replace the cap after use to prevent ink drying and store the pen horizontally or with the tip up if unused for extended periods.

Usage recommendations

Use on standard writing paper for best performance; very glossy or coated papers can reduce ink adhesion and drying speed. If the pen skips after storage, try writing a few short lines to restore ink flow. Keep away from high temperatures and direct sunlight to maintain ink consistency.
