Lockdown and terrible sleep patterns have me at a minor stage of madness, so at 5 this morning while I was considering grabbing the air rifle & silencing some of the birds that had apparently gotten hold of megaphones to sing their dawn chorus outside my window...
I decided instead to do a very unscientific test (see also: dirty) on my all time (so far) favourite ink for practicality, Sailor Sei-Boku - Pigment Blue/Black.
The test was carried out as per the description on the index card, what I didn't have room to fit however, is that the index cards are cheap (more like thick paper than index cards, probably 140-160GSM and fairly porous), the degreaser in use was 151's "Elbow Grease" and the nib used to write all text on the index card was a Bock fine.
I think I am most surprised by how little effect pen flush (Monteverde brand) had on it! The only thing that really did anything was the degreaser. As expected, water did absolutely nothing.
Rear side confirms it, the degreaser had the most effect while actual pen flush only managed a 'flesh wound'.
Until Sailor Sei-Boku starts dissolving my pens (unlikely, since it isn't an iron gall ink) I don't think I need to quest for a tougher, more well behaved ink.
So far, on my journey to find a "bulletproof" ink I have tried offerings from Noodlers (massively ill-behaved, over saturated, too wet 90% of the time regardless of colour, but some are definitely worse than others! Looking at you Sun Never Sets!), KWZ (extremely well behaved & beautiful colours, but not really truly "bulletproof", 'just' iron gall) and De Atramentis (the black behaves very well, everything else I've tried in the "Document" line has had properties very similar to Noodlers). Sailor Sei-Boku (haven't tried the other two offerings yet) is by far the best (IMO). Not only is it nigh on indestructible on paper once dried, but it also has properties, yes, properties! It shades extremely nicely and even, on the right paper, has a hint of red sheen to it. Beautiful and practical, just like me! Okay, well...maybe not.
On top of all that? It tames the most cheap, nasty, course paper I have (Poundland/dollar store notebooks, grey recycled toilet paper...you know the sort!), with no bleed or feather!
Disclaimers - Apologies for less-than-stellar picture quality, taken with my ageing smartphone, any perceived feathering is due to that, to the naked eye I can see none.
