| Why was this JUST invented?? It's like the upside down ketchup bottle: the simple solution to a 100 year old problem just NOW figured out! I hope all pen companies use this design. Those Korean designers are awesome (and soon-to-be rich!) |

| pretty solution, but dumb. if you just shape the ink holder like the parker filling.. more ink and easier to make, just thinner walls on the broad part. |

| "Wider cartridge?" "No, we need to make it complicated." |

| but if there was less ink in the pen, the pen manufacturer could make more money by selling you more pens. |

| i don't think the ink lasts twice as long. i think the design allows you to place 2x the amount of ink versus the regular tube |

| Indeed, it's not like this solution is "revolutionary" and "just discovered"...you can widen the ink tube to make it last ten times longer not just twice. Don't be fool and think the pen manufacturers never thought of making the pen last longer... there's a good reason for keeping it as it is |

| I'm betting nobody will ever see this, since all of the other comments are from April 21, but I thought I'd put my two cents in. While I'm usually as cynical about companies as the majority of the above posters, in this case I don't think greed is the only motivating factor for keeping the ink tube thin. (I'm sure it's still in there, though.) I'm not in the industry, nor have I verified this, but I think disposable pens use capillary action to feed the ink to the roller ball. You'll see that most of them are open at the non-working end. If the radius of the tube is increased too much, then the ink will pour out when the tip is up, and the pen wouldn't work horizontally. There are a lot of pens that use sealed ink cartridges - especially refillable ones. Those can be made with a larger diameter cartridge, but I think they don't work as well, horizontally. The line of Fisher Space Pens (and I presume lines from other manufacturers, as well) use pressurized ink cartridges, so that they can write up-side down. But the ink also has to be made thicker so that it won't squirt out past the roller ball. This looks like it's intended to make a disposable pen last longer. And I'm sure there's some break-even point where the manufacturers can charge just a little more and the consumers can get pens that are ultimately cheaper and/or produce less waste. |

| The ink cartridge looks fantastic, such a shame to hide it inside an opaque barrel in use! |

| I don't know why these people don't like this. it is a good invention. otherwise we have to go to shops always to buy pens.as students it is really worth for us. |

| I have never had a problem with running out of ink. I lose the pen long before. |
