// mobile made of brass sheet. Measurements: roughly 12 in. wide and roughly 20 in. in length. Note: Brass naturally patinas (or darkens) as time passes, but a natural wax is buffed on for longevity of sheen. Over time, if you prefer the bright finish, fine steel wool will do the trick. +++ This is a wall hanging for [indoor] decorative purposes, not a wind chime. *** Not recommended for outdoor use.
