Here's a hard plastic, one-size-fits-most ring rendered in the shape and likeness of the power rings wielded by those who draw power from the coalesced compassion of all sentient beings!  Wait a second, didn't the Indigo Lanterns wield staffs?  Uh....ignore that.  Anyway, the reason you want it is because...it lights up!  Just 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 like to think you can handle basic electronics without maiming yourself, there are easy to follow instructions for replacing the battery (and operating the ring) on the flip side of the card.

Are you a fan of Green Lantern?  You a fan of the Green Lantern epic, the Blackest Night?  You were cool with the Indigo Lanterns and all their...hugging?  Hey, it's universal compassion they're mainlining, here!  These were one-time exclusives to the New York Comic Con, hence the higher price, but now....we got em'!  And that means......so do you!  Well, after you buy it.
