DescriptionSpecificationsFrequently Asked Questions
Uni-ball Signo UM-151 gel ink pens, also known as Signo DX, are known for their smooth writing and exceptional ink quality. And, to everyone's delight, there is a sea of colors and tip sizes to choose from. Find the perfect pen 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 waterproof, fade-resistant, and feather-resistant. Much of that is due to special viscous properties of the ink. The ink is viscous while in the barrel, but as it passes through the pen tip during writing, the viscosity drops. This results in smooth ink flow. Immediately after it hits the paper, the ink returns to its viscous state, which prevents feathering. You are left with beautiful clean lines that you can enjoy for a long time!

I love this pen. It writes smoothly, and the ink is a deep, pine green that looks great no matter where I've used the pen. The color is subtle (it doesn't scream "I'm GREEN!") but still looks unique.

Love this pen, it is...

Love this pen, it is quickly becoming my favorite. Writes rather fluidly for a 0.38 mm point. In fact, I am extremely impressed with how small I am able to write, without skipping or any problem whatsoever. It reminds me of fine writing instruments I used as a draftsperson many years ago. The green-black ink is a wonderful color, more of a pine green. I love writing with it so much that I plan to order more in different colors to use for both writing & drawing. At this price I can afford to indulge. Thanks JetPens.

The most critical element...

The most critical element of my search is to replace a professional dark green [Black Green; Hunter Green; Forest Green] ink with fine tip & ease of writing. I had a pen that was great fo15 years that is no longer available. I feel like Goldilocks and the 3 Bears. Gel pens are great for writing especially large volumes. I purchased a quantity of both
(1) Uni-ball Signo UM-151 Gel Pen - 0.38 mm - Green Black - Great colour, however very scratch writing.Perhaps a 0.5 mm tip instead of the 0.38 mm.
(2) Zebra Sarasa Retractable Gel Pen - 0.7 mm - Forest - Can live with the colour but a bit too dark (in some lighting it appears black). The writing was very comfortable smooth but the tip was a bt too large and made things more messy and consumed significant more space that the 0.38 tip.
So I am hoping for a Goldilocks solution of one in between that is 'just right.!'
I need some help - is the Zebra Sarasa Retractable Gel Pen available in 0.5mm? Is the Uni-ball Signo UM-151 Gel Pen available in 0.5mm? And these requests MUST be a dark green - Hunter Green or Forest Green or Black Green;
[Or has the Sanford unibal Gel Grip Forest Pen 0.7 mm that I used for 15 years resurrected?]
Help welcomed.

At first, I wasn't sure about the color, but it has since grown on me. It's a pretty great color really, a bit of an military green actually.
