Five of the six hooks visible on the top slatwall groove differ, and two are crooked. Visible are two matching One-Piece All Wire Metal Plate Slatwall Scan Hooks, a Flatback Safety Loop Hook, a One-Piece All Wire Straight Cut Single Prong Display Hook, a One-Piece All Wire Ball End Display Hook, and a Straight Cut Single Prong Display Hook of a different length. Maybe such visual clutter only disturbs me because my company makes hooks, and takes pleasure when they can be crafted into a good display.
