I haven't done a 'quickie' ink review in a while, and some of my thoughts on the approach have changed in the meantime.
Drying time: Long. Exceeds 30 seconds on Bloc Rhodia 80g/m² notepad paper. At 45 seconds (not shown), where the horizontal and vertical strokes in the digit '4' intersect, colour still came off and smudged readily.
Water resistance: Mild. There's a fair chance you'll be able to read what was there before, after a minute or so under the tap or in a bath, but the colour that come off already dried writing into a water droplet or onto a wet cotton swab could well render that faint shadow illegible.
Flow: I'd say more wet than moderate, when you compare the colours seen in the writing and the long straight lines against the multi-pass bar done with a Pilot Parallel pen; the 'single-pass' colour is not often seen.
Feathering: Not on Rhodia paper, but because of the ink's 'wetness', I've seen it leave 'woolly' lines on other types of paper.
Shading: Some, and the potential is definitely there, but because of the ink's 'wetness', it's more of a case of the 'two-pass' colour transitioning straight into sheen territory, overwhelming the shading effect unless one is using a very 'dry' pen.
Sheen: Evident even in narrow lines coming out of a 'Japanese fine' nib, on various types of paper I tried.
Show-through: Not enough to warrant mention.
Bleed-through: Evident with three or more passes of the ink. Interestingly, it's not just the amount of ink left wet on the surface of the page to dry over time; there is no bleed-through where ink pooled at the end of a stroke with a Pilot Parallel 6mm pen ever with two passes. Contact with moisture/water for 60+ seconds did not cause any (more) bleed-through.
