Here's a hard plastic, one-size-fits-most ring rendered in the shape and likeness of the ring that rules them all...the White Ring!  This ring draws power from the White Lantern Power Battery!  The White Battery holds the White Entity!  The White Entity is responsible for...the imposition of creation on the canvas of static nothingness!  Well, that's how sentient Death sees it, anyway.  All right, let's get to why you're really here: It lights up, baby! Turn the ring upside down and use the side ridge on the included key to switch the light-up function on or off!  Woo!

The face of the ring measures about .75" across in diameter and about 1.5" high from the top of the face to the bottom of the band.  Each ring is powered with a replaceable CR 927 Lithium battery that can be....replaced.  If you're handy-ish, there are easy to follow instructions for replacing the battery (and operating the ring) on the flip side of the card.

Now, stop atomizing all the heroes you resurrected and get back to protecting the Parliament of Trees!
