An 81.6 mm Pocket Pen: Mini Brings Full-Metal Build to the Pocket
A pocket pen built for quick, in-between writing: 81.6 × 10.5 mm, about 9 grams, eight colours, sized to the universal miniG5 short refill. It also ships as a standing gift with Dog 2.0 orders.
Most mini pens fail on two counts: they break easily and refills are hard to find. Mini was briefed against exactly these two — an all-metal machined body against breakage, and a barrel sized to the universal miniG5 short refill against the supply problem.
"Take only what you need — it is the regular in the backup position." — the design stance behind Mini

Where it goes
Moonlight Silver · studio retouch: brushed metal barrel, translucent clip
A suit's inside pocket, a card holder, the side pocket of a parent's bag, a car slot — at 81.6 mm it never bulges. Signing on the go, a shopping list with a toddler in tow, a note mid-citywalk: this is its home ground.
Everyday carry: the side pocket of a bag, always within a one-second reach
Also, honestly
A short barrel feels different from a full-length one; for long writing sessions a full-size pen still wins, and larger hands will notice the compact size. Its role is the regular in the backup position — it lives in the pocket and shows up when needed.
Mini currently ships as a standing gift with Dog 2.0 orders, and is also available on its own.
