Damn near perfect. I've tried pretty much all lettering pens you can get in
Japan - and this one is the best for a pocket-pen. The refill works just fine as complete pen. Looks well and is safe from leaking.
The grip and all is good, so I don't see why one should get the clunky shell.
That makes it also relatively cheap.
It's a felt tip, and so over time the line loses precision and punch. But I
still give it 5 stars, since in the same category all pens have the same issue.
Until then this one produces a very fine line (with some flexibitiy in the tip)
- for all I know, the sharpest compared to other normal lettering pens.
Never store this eraser next to plastic objects - it starts to dissolve them!
Weird that no one else mentions it. This thing destroyed some pens and erasers
of mine, by turning their plastic into goo - that strangely doesn't harden
again. I had several of these erasers, so I don't think it's a single
manufacturing mistake. Must be some nasty chemical in there. It also started sticking to plastic surfaces I stored it on.
So yeah. It erases fine. And the black residue is practical for easy cleaning.
It also looks neat... but this is just a no-go for me.
I do not know why this product would get any reward. Ok, it looks nice, but I'm
sure the designer never used it for erasing - because its useless!
The shape makes it worse than a standard one, as there are less corners you can
actually use for erasing. And especially when you come to the end of one of
those cubes, it just gets bad.
Sorry, but this is just bad untested design.
I'm using this since years now after I found them in Japan. After trying
literally hundreds of pens this is the one I stuck with. It creates a great line
- it allows perfect control over the line width, by being a bit firmer than
other brush pens.
Additionally it is good for transporting in a pocket - it never runs out (just
sometimes the ink gets very fluid, I have not figured out why yet). It's perfect
if you're learning Japanese writing - learning a nice style and stroke order
will come more natural to you.
Only drawback is that the tip quality goes down fast - especially the very fine
top and fluidy goes away fast - you have to switch every month or so (depending
on the use of course). A more durable tip would make this the perfect pen.
