I'm really keen on purchasing my first Japanese pen and really like the Platinum urushi Izumo, red coloured pen. The problem is that I want one with an extra broad, BB nib. I know that Japanese broad is more like. Western medium, and medium nibs just don't work with me. I want to have it custom ground to CI. It appears that retailers say that extra broad is not available with this pen, however, Mottishaw's nibs.com do have an extra broad as an option. Any insights into this? Is it possible for retailer to order one from Platinum, or is this not possible. I really like the pen, but not the rather narrow nib change ( pun intended)...
