Do you often have trouble finding your keyhole in the dark? This glow in the dark sticker makes it a lot easier to find the keyhole and open your door. The sticker recharges in daylight and glows in the dark.
You can also place it on a light switch to find it in the dark.
Whenever you turn off the light (and it's really dark) the sticker starts glowing. After a while the glowing process reduces slowly.
Each set has 3 stickers for keyhole and light switch.

PROCESS GLOW IN THE DARK
Another name for glow in the dark is phosphorescence or fluorescence. It simply says that the product absorbs the light and releases it in the dark. This can be done with phosphorus, but also with newer chemical compounds. It must be very dark to get a good effect. If it is not dark enough, the glow in the dark will not light up. The glow time depends on the workable material in the material and the amount of light stored by the product. This may vary from a few minutes to a few hours.
