Ring moulds or 'Mousse Rings' as they are sometimes called, are the perfect way to get neatly stacked items onto a plate as well as being moulds to hold things together whilst they set. Being made from stainless steel, they are non-tainting and very hard wearing plus have the advantage of being dishwasher friendly. There is no reason why, with proper care and use, they should not last a lifetime, yours that is!
