No, these are not bracelets, but instead keychains. They slip over your wrist for when you need those hands free-such as pumping gas or carrying groceries. And because these are constructed with durable resin beads, they can take the beatings that we give our keychains. These beads are LARGE, but that is so that you can find your keys when you need them. No more wasted minutes digging in your purse looking for them. Since these are made from resin beads, they are very lightweight...only weighing a few ounces. They are assembled with a stretch cord system to easily slide over your hand and wrist. One size fits all.
