I couldn't find any information on the barcode 00009854258300 being reported as Nike Air. It's possible that this barcode is not associated with a legitimate or popular product.

As I couldn't find any relevant information, I must inform you that I couldn't verify the authenticity of this product. However, I can suggest some steps to help you identify the product:

1. Check online marketplaces: You can try searching for the product on online marketplaces such as Amazon, eBay, or Walmart's website to see if anyone is selling it.
2. Contact Nike customer service: If you suspect that the barcode is indeed associated with a Nike Air product, you can contact Nike's customer service department to inquire about the product.

Regarding prices, I couldn't find any information on the current market price of this product.

As for warnings or concerns related to the product, without more information, it's difficult to say. However, if the product is indeed a consumable item (such as food or medicine), there may be health-related disclaimers associated with it.

Please note that if you do find a product matching the barcode, I'll only mention any health-related disclaimers if the product is a consumable item.
