2-Sided Giant Acrylic High-Def Keychain. You won't see keychains with this kind of craftmanship anywhere. One side reads "Never Forget 9/11" while the other side features the "K-9 Recovery Dogs of Ground Zero." High gloss, durable polished acrylic oversized at 2x3 inches and 1/4-inch thick. True conversation pieces, classy and respectful. Image by Official Ground Zero Photographer Gary Marlon Suson.
