Behind the Design

The BR-KNE33 refill was developed alongside Tombow's Monograph ballpoint pen series, which prioritizes a clean, minimal aesthetic and precise writing performance. The needle tip design addresses a common frustration with traditional ballpoint tips: the wider barrel around a conical tip can block your view of exactly where the point meets the paper.

By narrowing the tip body into a needle form, Tombow opens up the sightline around the writing point, letting you place characters and figures more accurately. This is paired with ultra-low viscosity oil-based ink, which reduces the drag typical of standard ballpoint ink while keeping the line crisp and consistent. The result is a refill that bridges the feedback of a gel pen with the durability and page-resistance of oil-based ink.

A needle-tip oil-based ballpoint refill for the Monograph series, built around a wide-visibility tip that keeps the writing point in clear view. The ultra-low viscosity ink flows smoothly at 0.38mm, making it easier to write small characters and precise figures without obscuring your line.
