What does "dusty appearance" indicate regarding a product?

The term "dusty appearance" refers to a sign that a product has likely been on the shelf for an extended period without being sold, which can indicate that it may be stale or damaged. When products accumulate dust, it suggests that they have not been handled or moved regularly, raising concerns about their freshness and overall quality. This is particularly relevant in contexts like retail, where the presentation and condition of merchandise are closely monitored to ensure customer satisfaction. In contrast, a new product or one with high sales would typically not show dust, as it would be regularly rotated and restocked. Hence, a dusty product serves as a visual cue that warrants further inspection before sale.
