Zebra JF-0.5 Sarasa Gel Pen Refill - Blue Black - 0.5 mm

I love the colour pigmentation of Zebra Sarasa's blue black gel ink. It's dark like Muji but doesn't have the overly runny consistency, so this one hasn't bleed through paper for me - I use Hobo Weeks, Sterling Ink and Hungry Gal Studios which all use a variation of TRP.

Overall experience is good. The feedback from the nib on the refill is good. It isn’t as smooth as some pens, but it isn’t scratchy. It does seem to reflect back to you differences in the paper you write on. It was comfortable to the hand when in Zebra pen body, didn’t blot or skip, and has a good clear line. I’ll be getting more of these.

very good as usual, great pen and ink
