By eliminating the corners of the tip and the signo ink of the new formulation, the frictional resistance between the pen tip and the paper is reduced, and a smooth writing taste is realized. The Uni-Ball Signo RT1 is a one-motion design in which the joint between the grip and the shaft is inconspicuous.

    Very good super-fine pen

    I love a 0.38 for squeezing notes into the small fields of my personal sized planner but personally I found this model skipped a bit and wasn’t as smooth as my Uni-Ball 0.38 P. I will still get good use out of the Signo RT1 though and my opinion of this pen has no effect on my love for Rosie Papeterie products and service which is always 5-star

    Review by Mercedes

    I love the grip of the pen and also the fine tip. It wrote smoothly and didn’t smear.


    Love the gel in this

    Love this pen

    Very smooth writing and the tip is thin perfect if small writing is needed.
