Yasutomo was a brand I was not familiar with until JetPens started stocking a few of their pens last year. They originally started out in the 1950's as an importer/exporter of Japanese and American goods between the two countries and later got in to designing their own products, such as this Y&C Stylist Gel.
While the Violet gel ink color looks nice on the page, there aren't too many other positives to be taken away from this pen. The design leans very much towards the Pentel R.S.V.P. and is right in the same price range. That's not a knock on the Stylist Gel per se, but if you are looking for innovation you are going to have to look elsewhere.
The writing experience is poor as well. The tip is scratchy and there is a persistent clicking sound when writing. There is also a sharp plastic ridge near the grip area of the pen. If you grip too low it will dig into your fingers and become uncomfortable.
You aren't going to go broke trying the Y&C Stylist Gel but I would pass and go for that extra cup of coffee the next time you are out.
