Received this a few days ago & broke it out today to put a thin shaded border around paper pieces & mats. The chalks are smaller than I expected & they DO create dust in the tray. I had to be careful it didn't migrate. Worst is that I followed directions, but the brush holds very little color. To create a 1/8"x2" line, I had to return to the color 3-4 times. It doesn't spread out at all. Yes, it sticks, but in a tiny area. It was lots more time & work than I expected. This is not for big or very dark jobs. I can't imagine doing a big stencil. Good news is that for small areas or photo tinting,it works very well and it does stick. Colors are great. The eraser works for the first minute or so, then it's permanent. Rub the brush on the eraser between colors, and there's no transfer. I'll use it, but not as much as I hoped.
