Four colours. One mechanical pencil. One beautifully compact pen
The Uni Jetstream 4+1 Lite Touch is a five‑function multi‑pen: four 0.5mm coloured pens plus a mechanical pencil, all in one slim barrel. It uses Uni’s Lite Touch Jetstream ink, a lower‑viscosity version of the classic Jetstream formula that flows even more smoothly while keeping the same rich colour and fast‑drying, smudge‑resistant performance.

Colour selection is handled by sliding switches near the top of the barrel; the sliding pocket clip advances the pencil lead, and a small eraser is hidden under a removable cap at the top.
 
This model was recognised in the 2025 Japanese Stationery Awards, where the Jetstream Lite Touch family won the Functionality Award, and the Jetstream 4&1 Lite Touch took Best Multi‑Function Pen. Judges highlighted its ultra‑smooth, low‑resistance writing and the practicality of having four colours plus a pencil in a shorter, lighter body that fits easily in small cases.
