Does not work at all
These don’t work at all. I used part of my grant money from my school district to get these, just to find out you have to press down very hard to get any kind of color, and even then only the very bottom of your hand will make any impression on it and the color is extremely faint and vanishes almost immediately. The heat from your fingers alone will not make any sort of color appear. The pictures are extremely deceiving.
