Enjoy seeing your phone change colors with this heat sensitive backing! This self-adhesive laser cut backing will change colors in the range 90 to 95 degrees F - or just below body temperature. At only .005" thick, it'll fit nicely under any bumper you put on your phone.
Watch as the backing changes color with heat from your hands, pocket, or while playing music, surfing, or on a phone call! Check out the demo video on YouTube.
The heat sensitive backing's colors range from black (cold), all the way through red, yellow, and green before arriving at a deep blue (hot).
Also available for the iPhone 5, only from RF Laserworks!
