Flicking the ink cartridge...
August 16, 2012
Flicking the ink cartridge will recollect the ink at the tip when it separates in most cases. My mom taught me this to rescue the pens I hadn't used since I bought them in Japan.

That being said, I adore these pens. I have a full set in the .3 and .4 sizes in all 10 ink colors, plus a .5 mechanical pencil, scattered between two 5-slot and three 4-slot pens. I bought my first ones in Japan while on study abroad, but I avoided using them when I returned because I was afraid of running out and never being able to replace them. Then, I found JetPens, and my favorite writing tool's refills, and have used them almost exclusively for a year now.

I've had these pens for about 9 months in both the .3 and .4 sizes. I purchased all the colors in both sizes. All but one of the ink cartridges has segmented out the clear gel and ink so that I can no longer write with the pens. They are always stored horizontally, but somehow the clear gel is now between the ink and the pen tip. Do not buy, they are not nearly as good as the normal Hi-Tec-C pens. Previous to this happening I loved them and used them all the time. REALLY angry at the amount of money they wasted.

I love this pen -- when it works. Unfortunately, just when I get comfortable with it's reliability, it shoots craps. I'm beginning to believe that the problem occurs when I leave the desk lay flat on my desk overnight. At some point the next day it will simply stop writing even though there is plenty of ink still in the cartridge.
Very Disappointing - and very expensive to keep changing the cartridge when it's not empty. I have not found a way to make it start writing again - not like other pens where you can scribble on the bottom of your shoe to get it going again - or lightly hold a lighter to it -- nothing works.
Love it when it works, but it never keeps working -- I've used it off & on for the past year or so. Won't buy another that's for sure.

I love these pens! They are the perfect size. Easy to write with, and easy to load in the pen.

The only problem is that they run out pretty quickly. This system is the perfect solution to carrying around tons of pens!

Perfect! It runs out a bit fast, but flows smooth and easily as usual. Really fun to pick out the colors and stock your pen barrel yourself, too!

The ink quality is nice, the smoothness of the tip is nice but if the ink is going to run out that quickly then that nullifies everything that is great about the pen.
My classes started in around the 24th of August 2015, it is now September 30th 2015 and I no longer have black ink.
I bought three pens that hold 10 colors plus a pencil and an eraser.
I was very disappointed.
I just opened the rest of the pens to check the ink level and the rest of the colors are at a little less than the halfway mark.
I have used other brands of pens/ink that were able to fill multiple notebooks before running out of ink. This hasn't even filled a SINGLE notebook.
It is just the start of the semester too.
I was really expecting for them to at least last me the entire semester....
Even though the pens that fit these ink cartilages are great, this ink cartilage really does a disservice to them.
These very pretty pens will now become pens that I keep in my purse incase I may randomly need a pen at times.

The ink flows greatly on paper, however I think that the size of the font when writing is too big, it looks like 0.7mm in my opinion. I thought this was 0.4mm, well I guess I'm wrong. When comparing to the Uni 0.38mm refills, these were thicker, the ink flows quickly that it'll leave an ink dot (if you get what I mean). Definitely won't buy this size anymore, I'm changing to the 0.3mm, if that disappoints me. I'm going to give up on this brand for multi pens.
