Sharpie Cosmic Dark Matter Gray, Ultra Fine Point Permanent Marker

a warmer grey

This pen mostly worked pretty well for my purposes, but it is a warmer grey, which reads as a light brown or taupe at times. I didn't mind too much, but if you're looking for a more neutral grey option you might want to avoid this one. Mine did arrive with a crack at the back of the pen casing. It still worked fine, but I suppose it's possible that it affected the color, depending on how long it had been like that. I assume it just happened in transit, though.

Glad I found this one.
