Stylos non permanents STAEDTLER Lumocolor - Noir

Great pens but rarely have enough in stock at the store I shop at. Last time I made a purchase I told the woman at the cash and she said she'd order some in and let me know when they arrived. Still waiting to hear from her.

Two things:
1) these are exactly what was recommended in the instructions for my roll-up gaming mat, by Chessex, and
2) I have a laminated "scratch pad" version of a character sheet, for working out skills/perks/etc for particular specializations. These markers don't rub off very easily, until some moisture is used, which means less accidental loss of info while working out configurations.
I have, to be fair, mostly used the black, but it hasn't seemed to leave any trace of ghosting, after cleaning, on my laminated character sheet.
