Dear Customer,Please take a moment to read the whole of this listing, before placing your order. One of the most common problems we experience is from customers who do not realise the mould they are buying is not the right size or suitability for their intended use. If you have any queries about our moulds prior to purchase then please contact us first; we are happy to answer any questions you may have about our products.The main intended use of our moulds is for quick and easy forming of sugarpaste cake decorations. Full instructions for use are supplied with every purchase. Our moulds can also be used with other modelling substances such as polymer clay (Fimo, Sculpey etc), wax, resin, soap, embossing powder and PMC.The silicone rubber we use in our moulds can withstand relative extremes of temperatures (from -30\u02DAC to +250\u02DAC) for short periods. The material is soft and flexible, with inherently good release properties, making demoulding of sugarpaste decorationd
