I couldn't find any information on a product with the barcode 86947191636 and the name "Prom Queen Tiara Tweens No Size". It's possible that this is a private label or a specialty item that doesn't have much online presence.

However, I can suggest some alternatives to help you find more information about this product:

• Check online marketplaces such as Amazon or eBay to see if they carry this product.
• Contact the manufacturer directly to ask about their products and pricing.
• Check with local retailers in your area to see if they carry this product.

If you're unable to find any information on this product, it's possible that it's not a widely available or well-known item.

As for prices, I couldn't find any current prices for this product. Prices can vary depending on the retailer and location.

Regarding health-related warnings or concerns, since this is a children's accessory (a tiara), there are no specific health-related warnings or concerns that I could find.

However, as with any product, it's always a good idea to check for any recalls or safety notices issued by regulatory agencies such as the Consumer Product Safety Commission (CPSC) or the American Academy of Pediatrics (AAP).
