Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm -10 Pcs (Black)

Saturated beautiful writting from the begining to the end of each pen with out leakage. Moving is very smooth but not slippy, it is hard to find a better option than this one.

I have been using it for many years, it is a very good pen

I’ve been using the Uniball UM-100 since college - over 10 years now - and it’s still my favorite pen! The ink flows smoothly and dries quickly.

Comfortable in hand and black ink is fairly bold. Ink flows smoothly. Generally ink won’t smear ( I am not left handed) and appears to dry almost instantly. Ink lasts a long time and cost per pen is very reasonable when bought in packs of 10. Comes in different point sizes but I prefer the micro point 0.5. Other sizes available (0.38 really micro, 0.7 fine, and 1.0 bold).

I'm a huge fan of Uni-ball Signo pens, but wasn't paying close enough attention to the model numbers when I ordered these. I thought I was ordering my favorite UM-151 pens, not these UM-100s. My mistake. On the plus side, these pens have the same excellent writing quality that my favorites do. Lines are clean and dark, and the pens move smoothly across the paper. The caps are also very secure when clicked all the way on. On the minus side, the barrel of the pen is smooth--like, really smooth--and requires a strong grip to keep it from slipping during use. The UM-151 has a rubber grip on the barrel which makings holding it much easier and more pleasant. I'll probably wrap some electrical tape or the like around to make it a bit easier to hold. So I'm satisfied enough with the pens, but they won't become my daily go-to. The UM-151 provide a better writing experience overall.

Best pens, super smooth, always write really well. 10/10

I love pens from Japan. I trust Uni-ball. This one is 0.5, not too bold, just works for me. As a college student, I need to write so many pages per day. Now I hate using any other pens. I'll come back after using out these 10 gel ink pens! ps. When the pen is new, it has much ink in it. When having a lecture, sometimes I need to take some notes, and for other time I just listen. If you don't wirte with it for a long time, ink will come out a little as it is new. After using a while, the words look much much more better! much much more!

I got 0.7 instead if 0.5

Good Quality Product, Fantastic Service.
