Uni-ball Style Fit Mystar 3 Color Multi Pen Body Component - Brown

I'm sorry this brand of ink/pen refills is very difficult to write with. The only way that the ink comes out smoothly on .28 and .38 sizes (only ones I have tried) is if you write with you pen straight up and down. If you don't write with your pen absolutely perpendicular to the paper, then the tip scrapes weirdly against the paper (you feel the edge that holds the rolling ball scraping) and the ink does not come out evenly, you keep getting areas where the line goes blank or goes light and it looks horrible.

I purchased Hi-tec-C Coleto at the same time to test them -- and those are AMAZING. no matter what direction you write in, I bought .3 and .4 size tips and both are amazing. For larger amounts of writing, the .4 is best because otherwise the .3 is quite thin. The .3 is ideal for taking notes in margins and having super neat handwriting which is very clear and awesome!!!!
