I truly love writing with the pens and how nicely they erase even though sometimes it does take some effort. They are my favorite pens now. They don’t even leak through my Bible’s pages but the paper is too thin to erase. What I absolutely hate however is how every single Frixion pen, and I have bought many pens and refills of various colors, leaves an inch of ink in it when it runs dry. No amount of tapping or shaking or coaxing can get that last inch to run through. What a waste! And to top that, the pen only gives you a warning of six- eight written words, if you are lucky, as it gradually fades out.
