Wonderful quality and construction for a low price!
I love it!
This model is able to fill about 2-3ml and it should last better than the Eco model. I ops for the fine nib but it doesn't really write as fine as some Japanese fine nib. Smooth wrtting experience though with this nib and generous flow.
If you are those people who like to write but finds ink runs out quickly, this piston-filled pen is a good choice. The nibs and the piston are easy to disassemble for cleaning. The nibs that I order (M) is smooth and properly tunes. You may need to put a little silicone grease (that comes with it) on the piston before you ink up your pen. It will turn smoother. With this price range, you couldn't get any piston filled pen as good as TWSBI.
My first TWSBI pen and also my first piston fountain prn and I am very satisfied with my purchase. The material of the pen feels solid and looks like it is worth more than the selling price.
Ink filling is easy to do and flow of the Extra Fine nib is very smooth.
Bought a extra fine. The writing performance and build is good. Best value over price. But it has fragile feed fins, broke some fins when try to pull out the nibs for cleaning (3-4 fins breaks and tilted but didn't fall off) . It's a common procedure to pull out the fin and nibs during maintenance for such type of fountain pens. The last part a little disappointing. Overall it's a great pen. Just be careful when you dissemble it during maintenance.
It is very smooth, and the transparent body looks gorgeous when i fill in the pilot iroshizuku fuyu gaki ink. However, the operation of the ink system is a bit tricky for the beginner users and the introduction is not clear enuf, anyway, i will gv it 5 stars due to its smoothness in writing...
Top marks - because not only does this Pen offer a nice example of a demonstrator, it also is a surprisingly good, smooth writer. Comfortable and sturdy enough for me to try out the more exotic inks. Recommended as an every day carry as well.
