GHOST BUSTER: Channel your love for Slimer (and all things that happen after the sun goes down) with the Glow-in-the-dark POW! Chain; the exclusive pop art piece is a collaboration between RSVP Gallery and Ambush Designs. The capsule collection includes two POW! Chains, one with a black chain and one with a matte green chain. Both necklaces feature a matte pale green POW! pendant that glows in the dark, meaning now you can finally retire your flashlight.
