Query: Good markers.

We do a lot of dry-erasing where I work and we struggled for a while with markers that would dry out easily. Whether it was a issue of people not replacing the caps or just faulty markers, I don't know. But I do know that these markers have held up to the test of being repeatedly used and occasionally being left uncapped. It's been well over a month and the 6 marker set that I took in is still going!
