Each bottle is cut and hand sanded, for a safe product. We hand painted each bottle with a unique personalized design. For a more polished look we add a handcrafted beaded sun catcher and a pendulum that accents the hand painted theme. .A metal ring or wooden ring is places with-in the bottle to create a lovely sound in the wind. It hangs from a sturdy jack chain and is able to twirl freely in the wind by the swivel attached to the hook.
