I used to carry a stainless steel Fisher bullet pen, but I loaned it to my Mom to use while she was bedfast, (so she could write upside down in bed) and she lost it and I’ve not seen it in years. I found a pen I prefer though in writing feel to my space pen. It’s a gel ink pen from Walmart. It writes smoother on the paper, and the ink is darker and easier to read. The downside is, it takes a while to dry on glossy paper and can smear easy when wet. This can especially be difficult for a lefty like me.
