This rose will last forever and remind your Mum how much she is loved each time she sees it. These sculptures are delivered in an unrusted state should you wish to keep like this you must either apply a sealant protection or matt lacquer of some kind to the bare steel or keep it in a very dry location. These sculptures are intended to rust & will do easily subjected to our British weather however you can speed up the process by spraying some water on the surface every few days or alternatively add a mixture of 1 part household vinegar to 20 parts water spray or brush onto the surface a couple of times to quicken up the transformation. The steel composition at molecular level rusts only on the surface and does not penetrate deeper. It is an expensive steel that lasts a lifetime.
