The Uniball Signo RT Gel mini Hack

If you like fine gel pens but would prefer a smaller form-factor, this instructable shares how to modify a 0.38mm gel pen cartridge to fit inside of a G2 mini pen barrel.

The original how-to was posted on my blog in Spring 2006.

Step 1 G2 mini vs. Uniball Signo Comparison

Here you can see how the G2 mini and Uniballl Signo compare side by side. The G2 mini is about 4.5 inches long, compared to 5.5 inches for the Uniball Signo. For pocket-ability, that reduction of an inch means quite a bit — making the G2 mini well-suited for pockets.

Ha! first to comment! by the way... HUH? no offence, but I don't really get the point.

Point being you can't get fine-line 0.38mm cartridges in a G2 mini barrel, this allows me to do it.

What's so special about 0.38mm? sorry, but I kinda like the 50c ones ;)

0.38mm dry faster, so I use them with my Moleskine when I don't want the ink to smear. :-)

OK, Thanks
