Touch/heat sensitive adhesive colour changing vinyl film that reacts to temperatures between 77 to 86ºF (25 to 30ºC).

Initially black, this sheet goes red, green, blue with increasing temperature, and finally to black again.

To remove the protective backing from adhesive, press down firmly with fingers in center of sheet and smooth outward, in each direction in turn, to ensure that no air bubbles are trapped between the sheet and the surface.

Great for educating students and as a notebook or mobile phone cover.
