I was a little apprehensive about these but got the black ink kit on sale from an art store.

It definitely stains. I think it might contain butimen. All in all it's a good ink, leaves a ghost (size depending on solvent used to buff and time spent buffing).

A little expensive but a good mop.  5 of 5 Stars!

Great marker overall, however, DO NOT add flowpen to this. It makes it super thick and when you write with it, the ink does not dry. So other than that, I liked it.  5 of 5 Stars!

Question: What’s a good hard buffing dye ink to refill in this after it runs out?
