The SEA SHELLS Silicone Mould is made out of a silicone system specially formulated for use in food and confectionary and complies to FDA regulations. Includes 10 different shell designs. Mould is approximately 7.5cm x 7.0cm. For best results use with flowerpaste, modelling paste, fondant (with tylose as hardener), marzipan and more. For best details, tap in small amount of paste with a small rolling pin. Roll gently over the silicone mould and remove excess paste with a blade tool rather than a knife to avoid damaging the sugarcraft silicone mould. For easy release, the sugarcraft silicone moulds can be lightly dusted with cornflour.
