Here's a hard plastic, one-size-fits-most ring rendered in the shape and likeness of the power rings worn by those who wield the coalesced powered of universal Hope, the Blue Lanterns!  Oh, just be sure you have a Green Lantern nearby so your ring actually works!  And now, the reason you're all here....These simulated Blue Lantern rings actually light the #### up!   Turn the ring upside down and use the side ridge on the included key to switch the light-up function on or off!  Thank us later!!

The face of the ring measures about .75" across in diameter and it's 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.

Are you a fan of Green Lantern?  You were all comic-crazy-head while reading the Green Lantern Epic, Blackest Night?  Yeah?  Then let your collection of rings linked to the very essences that permeate universal sentience start here!  These were one-time exclusives to the New York Comic Con, hence the higher price, but now....we got em'!  And on that day, the universe....shivered.
