my local art store had like 30 of them on a shelf so i racked like 10 of them, I must say these are the shiznit. I filled em up with my own ink and they get maaaad juicy, just take some of the cotton sh*t out first.
I had the original H2B marker and I loved it so I decided to try this one out and I was even more impressed, its a nice marker overall (for f*cks sake, just google bitumen, not that hard)
