- Known for its smooth writing, exceptional ink quality, and outstanding selection of colors and tip sizes, the UM-151 (also known as the Signo DX) is one of our all-time favorite gel pens.
- Find the perfect one for any task, whether it's writing meticulous notes, marking your calendar, or decorating your scrapbook with colorful captions.
- Everything about this pen, from its solid construction to its carefully-formulated ink, ensures a wonderful writing experience.
- The sturdy tip does not bend or break, even with heavy-handed use.
- The pigment-based ink flows smoothly and is water resistant, fade resistant, and feather resistant.
- Much of this great performance is due to the special viscous properties of the ink.
- As the ink passes through the pen tip during writing, the viscosity drops to provide smooth ink flow.
- But immediately after it hits the paper, the ink returns to its viscous state to prevent feathering.
- You are left with beautiful clean lines that you can enjoy for a long time!

Excellent Product. Please let me know when other colours will be available.
1) Built quality: sturdy
2) Grip: finger friendly, you can write for long hours.
3) Ink colour: Blue, I love this light blue colour. Contrary to the blue ink of Zebra sarasa which uses purplish blue, this blue is very shooting.
4) Ink quality & tip: 0.38 mm bullet tip writes flawlessly and doesn't bleed through paper. Ideal for those with tiny handwriting. The ink is water resistant and quick drying.
5) Writing distance: writes longer than standard Muji gel refill.
6) Final option: very much recommended. You'll never regret for this purchase for sure.
