This is probably a dumb question, but I guess I'll ask anyway. The Hinderer site says the Fisher refills are the SPR4B, but I have to use blue ink in my pens to tell original legal documents from copies. My question is whether the SPR1 series of refills will work? It looks like they will, but I thought I'd ask some of you experts.
Thanks in advance.
