While I can say I've never been a big fan of the color that is Bay State Blue (BSB) I've never been a detractor either. Even though it stained my pen, sink and hands I shrugged my shoulders andfigured whatever, to each their own. I like Private Reserve Electric DC blue. Not everyone likes that.

I ordered one sample of BSB in 2011 and used it prretty much straight away in a Noodler's Nib Creeper pen. I  used most of it in a Rhodia Webbie. I noted that there was some show through and some bleed through, but not all of the time. I used it for journaling and for drawing.

Like my Fisher Space pen in red, it ghosts after a few years. What is ghosting? When an ink migrates through to the reverse side of the page and you can see a "ghost" of the image on the front. The ghosting with the Space pen red was dispersed and faded, very pink. Also each line had a halo of ink that had migrated away from the original lines. With the BSB The migration to the reverse of the page is intense and amazing. The original drawing or writing can be viewed (or read) in detail. I can see a slight haloing on the fron to fhte page. If I had filled both sides of the page with BSB it would no longer be legible.

Can anyone else report this effect?
