Inspired by our favorite stackable bangles, Mind Blowing Blue Resin is a swirly statement-maker that walks the line between fashion and function. The Original Big O® Key Ring is a one-size-fits-all bracelet key ring that can be worn on your forearm or above your elbow for hands-free simplicity. The patented, signature locking clasp clicks open and closed so you can keep your keys, phone and wallet in one central, secure location.
