OTR 984 Flowpen Marker Refill Ink 210ml set of 6 Ultra Permanent Colors by On The Run

The blue and violet are very very similar. I wish they’d made it a sky blue instead of navy. And the “violet” isn’t really purple. It’s like dark blue. It stains like crazy too which is good. Unless it’s on your moms white couch. It even stained the porcelain sink I left it on. I don’t know what’s in this stuff but it’s nasty.

other inks (from the same company?) are bolder and actually opaque, these are very transparent
