We have added architect nibs to our FPR nib lineup. Architect nibs are sort of like stub nibs but in reverse. Instead of a broad downstroke and narrow horizontal they do exactly the opposite and lay down a 1mm wide side stroke and 0.5mm up and down stroke. They do have to be held at just the right angle to accommodate the angle of the nib grind but when you get the hang of it they are a pretty unique experience. So far we have them available loose in both #5.5 and #6 sizes and available as an upgrade on select pens (presently FPR Tanoshii, Madras, Triveni, and Ambassador).
