I've been wanting to try BSB for some time now. I finally bought some and filled my Al-Star. It is all black, including the nib!! Pulled out some Clairefontaine Triomphe Stationery and started writing with a 1.5 mm stub on the Al-Star feed. WOW. Now I see what folks are so excited about with the BSB. It is such a wonderful shade of blue!! Staining is not a fear with the all-black of my Al-Star/nib combo. It truly is beautiful. Just get a black pen/nib set up & staining will not be a problem!!! BTW, is BSB normally scented? It seemed as I filled my syringe, to squirt into my T-10 cart that I smelled a pleasant aroma. Not knowing that much about inks that it, BSB, was of a smelly thrill !! Ideas?
