These work well and are a nice mix of colors ... but the blue marker STAINS my whiteboard

Thankfully, all the others worked well.

Of the 12 only 5 work well

These markers work well enough and does its duty on my board.

Other then that, I received a secured package of well working dry erase markers.

Fine tip works great for smaller writing and graphing

These ones work great for the first day or two

These work really well and after a couple months of kids using them they haven't dried out.
