I picked up a 3 pack of hero 612 pens and they arrived today. I like my 616s and have given all but one away to kids and others, so I thought I'd get some more. The 612s seem to be similar to the 616s, but with a gold cap and matching end piece on the barrel. The auction listed them as vintage, but the nibs and sacs seem to be identical to the 616 pens. The caps fit tighter, and I think they look a bit nicer.
I flushed one out, and loaded it with diamine denim ink. It writes smooth, and with a fine tip it flows nice, and is giving me no problems so far. I know some of you hate the 616s, but I've found them to be terrific little carrying pens, and are working great right out of the box. I'll have to give a follow up after I've used them a while, but so far they look like they will be great. Especially for $2.30 each. (BTW, I just saw a 6 pack from the same vendor for 9.90, so each one is only $1.65. I might have to get some more. )
