The Expo Lo Chisel Black Dry Erase Marker writes smoothly and wipes cleanly off with little to no effort. The marker offers a bold, deep black color. The marker also dries quickly.  The Expo does not have a strong odor. Another bonus is that you get 36 markers in the package so you do not have to worry about running out.  I use these at work to keep track of my tasks and the deadlines for each.  At home I use these markers to keep our chore list for the kids.  I am extremely pleased with how these work and highly recommend them.
