An apparatus comprises an elongate band and a magnet assembly. The elongate band is formed of an elastomer and defines a back surface, a front surface, a loop at a first end, a hook at a second end, and an enclosure. The magnet assembly is at least partially enclosed within the enclosure. The apparatus provides a convenient means by which to removably attach a bottle to a vertical surface. The bottle may thereby be stored out-of-the-way while not in use, but easily accessed.
