I have several Nahvular pens and I have fallen in love with the Original Plus Pen. I currently have 4 of them in a variety of nibs. I bought my first original Plus when the Nahvular team was at Dromgooles here in Houston. This order included the Matira Quartz (double broad nib) and the Lovina Graphite (stub nib) Original Plus Pens.
I love how the pens write although I have to admit that I can't see much difference between the Broad and Double Broad nibs that I have.
