50012367

I don't have any information on a barcode 50012367 associated with a product named "Best friend kolye". The provided barcode does not seem to match any products I have access to.

However, please note that there is a well-known Russian rapper and singer by the name of Kolyy, whose real name is Kolya Strukoff. It's possible that this might be the person being referred to in the question, but without further information, it's impossible for me to confirm this.

If you are referring to a specific product or item with this name, I would recommend checking with the manufacturer or supplier for more information on pricing and any potential warnings or concerns related to the product.
