Description
Our thermochromic paper changes color within the temperature range of 31oC (88oF) to 37oC (98oF). As the paper is held in your warm hands, the color will begin to change or disappear. As it cools, it changes back. The cycle repeats itself indefinitely. 8.5" x 11". This paper works best in Laser Printers and most standard copying machines. It may not feed properly in ink jet printers. Each package contains four brilliant colors:- Blue to White
- Magenta to White
- Green to Yellow
- Purple to Pink
