I used it in combination with a stopper. The product was beautiful with a stopper. This product is oxidized at the metal part and it will not be beautiful even if it is polished. I did not contact or change because the delivery date was approaching. Perhaps the manufacturer's shipping responsibility did not confirm it and sent it. Even if it is, the storage condition of the manufacturer is too bad. Keep it in a clean condition so long as you can not sell Managers! I think that it would have been better if you purchased cheap Chinese made in this way.
