Sun-Star Moomin Silicone Gel Pen
The barrel is the point: this Moomin pen is wrapped in a soft silicone skin, so it sits warmer and less slippery in the hand than a bare plastic pen. Underneath is a 0.5 mm gel ink refill in black - fine enough for planner grids and for writing in the margins.
What you get
- One gel pen with a silicone-clad barrel and clip.
- 0.5 mm black gel ink; the refill is replaceable.
- Two character designs from the official Moomin line.
- Made by Sun-Star in Japan.
How it writes
Gel ink lays down a dense, even line and dries quickly on uncoated paper, which is why it suits journals and study notes. On very smooth or coated paper, give the line a moment before closing the notebook. The fine 0.5 mm tip keeps small handwriting legible in narrow planner columns.
Grip and daily use
The silicone layer is the practical difference: it damps the pressure from a tight grip and stops the barrel from rolling off a desk. It also collects dust and lint over time, so wipe it with a damp cloth rather than a solvent. The clip is stiff enough for a notebook cover.
More Moomin and character stationery is in kawaii stationery; notebooks and paper supplies are in journaling, and the wider line is under Sun-Star.
Refills
The pen takes a standard 0.5 mm gel refill in the same body length. When the ink skips or the line goes pale, swap the refill rather than the whole pen.
Frequently Asked Questions
Q: What ink does it use?
A: 0.5 mm black gel ink. It dries fast on uncoated paper and suits fine handwriting and planner grids.
Q: Is the silicone cover removable?
A: No - it is fitted to the barrel. Clean it in place with a damp cloth and mild soap, and avoid alcohol or solvents.
Q: Can I refill it?
A: Yes. The body takes a standard 0.5 mm gel refill of the same length; replace the refill when the line starts to skip.
Q: Is it good for left-handed writers?
A: Gel ink is quick-drying, and the 0.5 mm tip lays down a thin line, so smudging is limited. Very smooth coated paper may still need a moment to dry.
Q: Are these official Moomin products?
A: Yes. They are Sun-Star stationery made under licence from Moomin Characters, with official artwork on the barrel.
