A seamless design focused on writing
While conventional gel pens often use clips, push buttons and rubber grips, TWIST takes a different approach. Its design centres on the act of writing. The pen is wrapped in a single-piece, soft silicone barrel, with neither a cap nor a push-button mechanism. Simply twist the barrel: the internal mechanism rotates and extends the refill.
As it twists, the silicone gently changes shape, seeming to “breathe” in time with the movement inside. The result is a writing experience that brings a greater sense of ease – and a little more ritual – to everyday writing.
Comfort and performance in everyday use
The soft silicone barrel feels gentle in the hand and naturally conforms to the fingertips when twisted, helping to reduce fatigue during extended writing sessions. KACO’s independently developed twist-to-extend mechanism is concealed beneath the silicone exterior, so the pen’s unconventional form does not come at the expense of the writing experience.
TWIST uses KACO’s SDRY gel ink refill. According to the company, the quick-drying ink dries in one second and offers a writing distance of up to 600 metres per refill.
Simplicity by design
By removing the cap and push-button mechanism, TWIST brings attention back to writing itself. Since its founding in 2011, KACO has followed a philosophy of “continuous innovation”, combining a minimalist, contemporary aesthetic with a focus on original design and user experience.
TWIST reflects this approach: its one-piece soft silicone barrel and twist-to-extend mechanism make the familiar act of writing feel more relaxed and effortless. The KACO TWIST pen’s design won Japan’s 2026 Good Design Award.
