Metal "LISTEN" Pendant Necklace

Tarnished bronze "LISTEN" pendant chain necklace. Full disclosure... I have no idea what the numbers mean, if anything (I believe they are just a style element). Chain and pendant are both light in terms of weight. New condition! Never worn. Closet stored with similar items. Not my style but maybe it’s yours! OS - unisex. Measures approximately 9 - 9 1/2” clasped.
