The box has a warning: kit it onto the listing

The carton says “not a toy,” “120V only,” or “ages 14+.” The live title does not. That is not a style miss. The shopper who needed that line will return the unit or open a claim. The Transformation Kit is how you put a pack warning on the listing from the pad, not from a legal guess.

Copy the warning the pack actually prints

Open one carton of the lot you ship now. Write the four facts. Then write the warning in the pack’s words, not a stronger version you “should add.” Photo of that panel. If the pack is silent, you do not invent a caution to sound careful. If the pack prints it, it belongs on the page.

Kit title, first bullet, and the attribute

Title still leads with product type and the count you ship. Put the warning in a bullet a shopper can scan, and in the matching Seller Central attribute if Amazon has one (voltage, age, intended use). Run free optimize on that ASIN only if the English hedges the line. Save after the hero still matches. Do not hide the warning in the last sentence of the description.

If lots disagree, stop mixing them

Old cartons without the mark and new cartons with it are two pads. Either sell through the old lot on the old facts or split the child. You stay responsible for Amazon compliance. When this ASIN is honest and the next marked child is waiting, Pro checkout is the paid path. Paying does not write a warning the pack does not print.

No fake reviews. No rank promise. You stay responsible for Amazon compliance.
