Rest assured that your lines will always remain crisp and clean with this new brush refill from Kuretake. Now, you can use your brush pen to your hearts content knowing that you can always replace your brush head if you ever damage or bend the bristles. Artists and calligraphers love Japanese brush pens because of their portability, convenience, and high quality. Brush refills and ink cartridges give you another reason to try them out!
FYI: While this brush pen refill will screw on the barrels of both the Kuretake
No. 8 and No. 13 Fountain brush pens, the cap of the No. 8 will not fit tightly
over this refill. The brush tip part of the. No 8 has a wider flange at the base
and is marked by a silver ring. The No. 13 has a gold ring near the brush tip.
Given their price points, it would make more sense to buy an entirely new No. 8
fountain pen and use this refill only for the No. 13.
I use this Kuretake No. 13 brush fountain pen front section only these days. I
originally bought the whole pen years and years ago, but as the body portion of
the pen has been taken over by the No. 40 nib I bought, I was left with this
front brush section alone.
The Kuretake cartridges seat firmly onto the feed, so I don't even require the
body portion. Instead, I now have a short pen with lots of control thanks to the
cartridge's snug fit. You can just use the plastic cap that it comes with as its
permanent cap, buy some cartridges, and you will have a compact pen, if you're
comfortable not having a pen body to screw the section into. I personally have
had no problems without the body; the cartridges really do fit that well. But
just to ensure you don't have any ink-accidents, I still wouldn't recommend
carrying this around anywhere other than inside your chosen bag or sketch kit.
As for function, there's a wide variety of line widths you can produce with
added pressure, and the marks left with quick strokes have a nice broken look,
while slow strokes with give you smooth, solid lines.
This brush pen might just be one of the greatest pens I own. I have had the pen
for 2 years (or so) and finally needed to replace the tip. I popped it in with a
brand-new ink cartridge and I was off and running again. I am so glad that this
replacement tip exists, otherwise I would have to buy the pen all over again.
