I know this has been answered already, but Im bored, so Im gonna answer again. The answer is no. Since there is nothing that would suck up the ink, or something that would pull the ink in (like suction) the ink would not fill up the pen. Thats how gravity works btw. There are pens that have disposable cartridges, some have built in refill pistons, an some can use a converter, and some are vacuum (suction). The disposable cartridges are pretty straight forward. Unscrew the pen, pull out the old cartridge, click the new one in. There you go. Pistons and vacuums, and squeeze are similar because they all use negative pressure. For the piston, put the nib in a bottle of ink, then twist the back end. The piston inside will move up the barrel, and pull the ink in. Vacuum are similar. Pull the back, then dip in ink, and let if fill. Squeeze work by squeezing the ink chamber which makes the inside smaller, then hold it in ink, then release pressure on the chamber, and it sucks in the ink. There are many converters that work on different pens that perform all the actions listed above, so mess around a little and find what you like the most. Also, if there isnt a cartridge for the color you want, you can always refill a used cartridge with a syringe and use that.
