Nice pens overall.
The single thing that attracted me to trying this pen out is the fact it uses Indian ink- the finish is superb, as dark as you would expect from this kind of ink.
The body seems a little cheap, compared to the Staedtler pigment liner anyway- the nib feels competent though and the brush nib is great for filling in areas… One of the other features of this pen is the vast amount of nibs fine to chisel something for every occasion from sketching to lining to filling.
Overall a great sturdy choice of pen for the artist who needs to more than just line work.
Hope this helps.
