[Mitsubishi Pencil](https://www.mpuni.co.jp/?ref=news.knockology.com) is giving its [Jetstream Lite touch 4&1](https://www.mpuni.co.jp/company/press/20261007-54357.html?ref=news.knockology.com) a machined aluminum grip, revised weight balance and five body colors. The **MSXE5-LA-05** launches in Japan on **October 15** at **¥1,430 including Japanese tax**.

Four ballpoints get most of the name, but the fifth function matters here: a **0.5 mm mechanical pencil**, with lead advanced by pressing the cap at the back. For people who keep both graphite and ink in the same pocket, the redesign changes the part of the tool they hold regardless of which writing point is selected.

## Metal where the hand meets the body

According to the [October 7 announcement](https://www.mpuni.co.jp/company/press/20261007-54357.html?ref=news.knockology.com), the aluminum grip is machined into a gently narrowing profile. Mitsubishi Pencil has also reset the weight balance. The release gives no weight figure, so it is too early to quantify how different it will feel.

The company describes a shorter overall body than its conventional Jetstream multipens and keeps the ink-color markings on the user-facing portions of the selectors. That makes the outside less visually busy while retaining the information needed to choose an ink.

## Five body colors, five writing functions

The lineup covers white, gray, black, red and green, shown together in the launch photography. Each has a grip painted in a related color, so the metal section reads as part of the body rather than a contrasting add-on.

## The pencil shares the redesign

“Lite touch” refers to the ink. Mitsubishi Pencil says it reduces writing resistance compared with its conventional Jetstream ink and addresses ink buildup and slipping on paper. Those are ballpoint-ink claims; the shared body and controls are the changes relevant to the pencil.

The pencil-side story is more straightforward: an everyday multipen with a new grip, a revised balance and a rear pushbutton for advancing lead. It is a useful design development for readers who want one body to handle notes, color coding and erasable work.

The announced price and launch date apply to Japan. Mitsubishi Pencil cautions that shelf dates vary by retailer; the release does not announce US distribution or a US suggested price.
