Let's get the famous story out of the way first. Everyone 'knows' that ballpoints didn't work in space, without gravity, so the Americans spent millions of dollars to develop a special pressurised ballpoint that did work in space. The Russians just used a pencil. Well, not really.
The Americans and Russians both used pencils. Paul Fisher, an inventer and pen maker, developed the pressurised refill, creating the 'Space Pen'. Then both the Americans and the Russians bought them from him and used them in space. Graphite is conductive, so snapped off bits of lead were considered a bit of a safety hazard floating around in a space capsule, so they were glad of a good alternative.
Oh, and standard ballpoint pens do work, and astronauts do sometimes use them, they're just not as reliable in zero gravity and extreme temperatures.
But Paul Fisher's Space Pen was reliable in these conditions, which makes it useful in all sorts of conditions, not just in space. They'll write better on damp paper, and greasy or dusty paper. They'll cope better in freezing conditions or excessively warm conditions. They have a much longer shelf life than standard ballpoints, too. They're just more reliable here on Earth, as well as in space.
The Bullet Pen is a wonderfully simple and practical design. Designed in 1948, it actually dates back to almost 20 years before the Space Pen existed. With the cap on, the whole thing is tiny, smooth, and well sealed so it's tough enough for life in pockets and bags. Uncap it and put the cap on the back, and it's a full-sized pen that's comfortable to write with, and uses the super-reliable and long-lasting pressurised Space Pen refills.
Measures just 95mm long when capped, but extends to 134mm when posted for writing. 9mm wide, 7.5mm at grip. Spiral-cut grip section makes it easy to hold. Brass body, with rubber o-ring to cap smoothly and with a good seal.
Supplied with a black refill.
