Uni-ball Signo RT1 UMN-155 Gel Pen - 0.38 mm

These are some of the very few affordable pens I can use due to my eczema. So I'm kind of forced to use them. At least they are very good.

Quite dark, comes with a blob of red wax to protect tip.

Best non-smudge pen. It is very smooth; just glides on paper.
