I am now officially over the Space Pen. See A Letter To My Pen for my list of gripes and complaints. The new pen, a Cross Ion, is great. It is a bit more chunky than I’d like, but it writes well and has a good visual indication of how much ink is left. Plus, both the pen and the ink cartridges come in a variety of colors. I have a silver/black one with black ink and a silver/red one with purple ink (so my writing can look like that of a 14 year old girl, of course!) Here it is in comparison to the space pen:
They are about the same length closed, both quite usable when open, with the Ion being more fat.
In unrelated photos, this Nerf gun is sitting on a shelf outside my office…
