Pentel has been making writing and art tools in Tokyo since 1946 — the brand that invented the fiber-tipped pen in 1963 and later developed Hi-Polymer lead technology that became the standard for modern mechanical pencil refills. Both firsts came from genuine in-house engineering rather than licensing, which is still how Pentel operates today.

The range covers the EnerGel liquid gel pen — widely regarded as one of the best smudge-free gel pens available, particularly for left-handed writers — the Pocket Brush Pen with individual synthetic bristles and waterproof pigment ink cartridges, the Brush Sign Pen for lettering and sketching, GraphGear drafting pencils, the indestructible P205 plastic-body mechanical pencil, and Ain Stein polymer leads engineered to resist breaking under heavy pressure.
