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!
