Uni Style Fit Single Color Slim Gel Ink Pen - 0.38 mm - Blue Black

Love love love these pens!!!

I choose this pen because it has a very thin writing line and it is gel so I was sure it won't bleat through my pages. They absorb a lot of ink if I use the wrong writing tool.If you like to write very small then this pen is your way to go.It also has a constant give off of color so it doesn't crack like other thin writing tools. I love it.
