Love it! Reasonably price! Comfortable!
The pen is absolute beautiful. You open it and you see it, just gorgeous.
The piston filling system works fine and smoothly and the ink flows nicely.
In a word, an 'eye candy' pen. Trust me. Can't stop looking at it.
This is a tricky one. In terms of writing experience, it’s no different from the ECO. A tad heavier and aesthetically a lot of fancier. If looks are important, then this will be a better option. But you’re only after a smooth writer, than ECO delivers just as well. I’ll still give it a 5 stars because independently, it’s a great pen.
It writes smoothly out of the box, and writes quite wet thus it is perfect for a shimmering ink. I am pairing it with the Diamine Caramel Sparkle. Write on Tomoe River paper to maximise shimmering effect. You will not be disappointed!
I have got the B nib and it writes smoothly out of the box. Love it!
