Car Accessory Boxes.

Differently depending on which of two cases you are in — and being clear about which is the single biggest thing you can do to reduce returns.

Universal-fit products — most phone mounts, cleaning products, fresheners. Say "universal" or "fits all vehicles" prominently on the front. It sounds obvious, but customers who cannot tell whether something fits frequently will not risk buying it. Removing that hesitation converts sales you were otherwise losing silently.

Vehicle-specific products — mats, covers, trim. State make, model and year range, all three, without abbreviation.

The year range is the part most often left off and it matters enormously. Model names span multiple generations and facelifts, and a mat cut for one generation will not fit the next despite the badge being identical. A customer who buys in good faith and finds it does not fit returns it — and reasonably feels misled.

Where a product covers several vehicles, a clear fitment list on a side panel works better than trying to compress it onto the front.
