Review on Mr. Pen Chalk Markers: 6 Pack Dual Tip Assorted Colors with 8 Labels - Perfect for Blackboard, Chalkboard, and Windows by Doris Tran

Very bright and easy to use (shake then squeeze to release). However, it WILL NOT WASH CLEAN. The photos show that I tried to erase "before myself" but the trace/outline of the paint is still visible. In the first photo, I use water and elbow grease while still wet. 2 photos - dried water. The third picture is alcohol - you can see he removed most of the board. The fourth photo is wiping after alcohol and using water to clean. 5th photo after the alcohol-water mixture has dried - you can see that it is discolored and has streaks. Don't buy if you want to delete. They would be nice to use to label something like a jar/party cup/"trendy" farmhouse/magnolia picture. I will not buy it again nor will I recommend it.
