Black GP-X Classic Markers with Xylene - 12 Count - 0918500 - GPX

These are the only paint pens we like to use they write darker then any other brand we purchased and they write smoothly which helps us since we are writing on many different surfaces rough and smooth. I highly recommend for any paint pen needs we write on wood, pipe (chrome and steel), grain bags, various large oilfield tools.

Markers arrived as promised and they were exactly what I was looking for.
