PME Closed Scallop Serrated Crimper . Made of high quality stainless steel ensure more durability. Suitable for adding design onto cake icings. Easy to use like a pair of tweezers; simply squeeze together to emboss sugarpaste or marzipan (this must be done whilst your cake coverings are still soft). Adjustable 'O' ring helps to get different sizes and adjustment with great comfort. The rubber ring is used to keep the crimper in place. Creative use of different adjustments can give an attractive look to the cake.
