At Karen Millen® Plug-in (possibly threaded) hooks extend from (through) a mirrored surface. A unique way to merchandise belts, and one that looks much better in real life than in a photo because reflected images visually appear in the same plane on your monitor. For product retention, 90° Tip Frontwires are employed. And yes the staff did keep the single the belts faced.
