Glow In The Dark Galaxy Nebula Doctor Who Tardis Heart Pendant on Cord and Ribbon Necklace

What do you get a whovian for Valentine's day? A beautiful, heart shaped T.A.R.D.I.S. pendant that glows in the dark. Her very own galaxy to wear around her neck. With a little bit of sunlight, or even the use of a black light, this galaxy pendant will charge and produce a beautiful glowing nebula in the dark on it's front. It is three dimensional with reds, greens, blues and purples. The pendant is about 1"x1" and comes with a cord and ribbon choker. Photoluminescent materials (commonly called "glow-in-the-dark") can absorb and store direct light energy (sunlight, fluorescent, incandescent, etc.) and emit that light energy when there is no longer a direct light source. When ambient darkness occurs, it becomes highly visible, lasting from a few hours to several days depending on the quality and color. Upon removal of the light source, the stored light is gradually released, the strongest glow is produced during the first 30 minutes of darkness. It then fades over a period until reintroduced a direct light source, so it may store energy again. It can be charged again, and again. If you have any questions about charging your purchase, please let me know.
