I couldn't find any information on the specific barcode 690291041358 associated with "GRINNELL CORP. 3/8X5 BLACK NIPPLE". It's possible that this product is a private label or a niche item, or it may not be widely available.

However, I can try to provide some general information about nipple clamps and breast shields, which are related products. Nipple clamps and breast shields are often used by breastfeeding mothers to help with latching issues or to protect their nipples from soreness or injury. They come in various sizes, materials, and styles, including black rubber or silicone options.

If the barcode is legitimate, I would recommend checking the product's packaging or manufacturer's website for any warnings or concerns related to its use. Some nipple clamps and breast shields may have specific instructions for safe use, such as avoiding extreme temperatures or using them with breast milk or formula.

As for prices, they can vary depending on the brand, quality, and location. On online marketplaces like Amazon or in specialty baby stores, you can find nipple clamps and breast shields ranging from $5 to $20 or more per unit.

Please note that if this product is intended for medical use or is a consumable item, there may be a health-related disclaimer associated with its sale. I couldn't find any information on the specific barcode, so I couldn't confirm whether such a disclaimer exists.

If you have any further questions or would like more information on related products, feel free to ask.
