• (c) a removable semi-circular resilient clip structure extending from, and attached to, a threaded female section of a second side of the attachment base, the second side being opposite the first side, wherein the resilient clip structure removably attaches to the attachment base using threaded sections attached to the clip structure, the threaded sections of the clip structure mate with the threaded female section located on the second side of the attachment base, and the clip structure includes separate and non-pivoted first and second arms which can be spread apart in order to receive an item and then released in order to close around the item, and
• (d) a magnetic backing component having a first side that includes a grip and a second side having a flat magnetic surface, the flat magnetic surface of the backing component having an opposite magnetic pole than the flat outer surface of the magnet, wherein the magnet and the magnetic backing component are magnetically coupled to each other such that (i) an assembly that includes the magnet, attachment base and clip structure is attached to an inner wall of a glass enclosure, and (ii) the magnetic backing component is attached to an outer wall of the glass enclosure.
