Sakura Gelly Roll Classic Gel Pen - White Ink - 08 Medium Point - 0.8 mm

They’re ok. A bit patchy.

Its perfect. I use it for defining fine lines over black watercolour painting. Great value for money.

I've found it very hard to find a white gel pen that will work, this one hasn't done it for me. I did hear good reviews about this so it may just be a faulty pen, but although it does work, it just doesn't work as well as I'd like unfortunately. As when it does work smoothly, it looks great!
