An improvement over the "standard" medium line width ink carttridges
I carry a Matte Black "Trekker" model Fisher Space Pen on my key ring. It's in my pocket, or on my desk, or out in my Truck at -15 or +95. If you're accustomed to slick gliding gel inks, well, you may want to try a friend's Fisher first. You have to apply more pressure to whatever paper you're using with Fisher all-weather, all temperature, 0 g. (any writing position) ink. The ink is not as "black", or dense or saturated as modern pigment inks. I thought that a wider line might be easier to read than the standard medium widths. So I tried the black ink in "Bold". IT HELPS. Fisher should offer their red ink in Bold as well.
