Here's a hard plastic, one-size-fits-most ring rendered in the shape and likeness of the power rings wielded by the Star Sapphires, avatars of the coalesced love of all sentient beings.  Trust me, the love you're thinking about doesn't really apply here.  But let's get to why you're really here.  You're here because this baby lights up! Turn the ring upside down and use the side ridge on the included key to switch the light-up function on or off! 

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 able to use a screwdriver without an impending emergency room visit, there are easy to follow instructions for replacing the battery (and operating the ring) on the flip side of the card.  These were one-time exclusives to the New York Comic Con, hence the higher price, but now....we got em'!

Are you a fan of Green Lantern?  You like the Star Sapphires coming in there and loving the opposition to death? Good, 'cause we got a ring for ya'!
