How come nobody realized about this? We use the pen with straight tube ink refill for a long time and often we are complaining about the low supply of ink to let us write more. However, the complains never result in any breathtaking solution. At least, until recently when Han Chi-hoon, Kim Yeon-soo, Park Byong-gon & Kim Sung-geun (yep, Koreans! I love Ginseng!) come up with this T&T Ink Chamber with Pen Ink Refill redesigned with spiral concept.
Instead have straight tube ink refill, these group of clever designers have bravely introduced us to their spiral tube ink refill that could hold up to 2 times as much as the ordinary ink refill on a single pen!
This means that you can write more documents, concept more drawing, sign more contracts, or do more hand copy writing task with single pen. Of course, since the ink refill tube is in spiral shape, it will take more space that the straight one. Which mean that the pen that uses this T&T Ink Chamber won’t be able to have a slim and fit design like what we have today.
IMHO, I don’t think it would be a problem if it’s just about a little fatter than ordinary pen. If the price sounds reasonable and I can save more than buying two pens at once, I’m sold.
Of course, it’s sad that this Spiral shaped T&T Ink Chamber is just a concept at the moment. However, the possibility to have something like this in the future is certainly there, as long as Pilot or any pen company found it interesting and take it to mass production.
