Made from high quality, food grade plastic, the cutters can be used to create beautiful flowers in a number of different sizes. There are some that are ideal for creating flower shaped cookies and biscuits as well as others that can be used to cut sugarpaste to create floral cake and cupcake toppers. The cutters can be used for a variety of mediums including: Sugarpaste, florist paste, modelling chocolate, cakes and cookies. Try using a number of the cutters together on different coloured fondant to create multi=layered flowers and use lustre dusts to paint on any additional features you would like. The cutters are also great for craft purposes and can be used with cold porcelain, salt dough and clay, however we would not recommend using the cutters with edible materials after using them with non-edible materials. Blossom cutters measure approximately: Small 33mm (1.3") Medium 45mm (1.8") Large 59mm (2.3") XL 75mm (3") XXL 94mm (3.7") XXXL 114mm (4.5"). To clean, wash in warm soapy water.
