The packaging states that these markers work on blackboards, greenboards, whiteboards, and glass. Only the white marker worked on the blackboard. If you're hoping to use the other colors, I'd go with a different brand. Unfortunately, this is the only brand I was able to find at Target.
The markers didn't show up on the black chalkboard I purchased for my daughter's 1st day of school, a couple of the markers didn't appear to get any color at all after pushing on them, and it left a residue on the chalkboard that couldn't be wiped off. I didn't try them on dry erase or any other surface because I had a specific reason I purchased them. I returned them.
