This is for a pack of Shaping Foam from Wilton to enable you to shape fondant and gum paste on thin and thick foam squares - great for cupping flower Centers and thinning petal edges. They all measure 4” x 4” 10.16 x 10.16 cm, but the depth varies - 1 x 0.7” 0.18cm, 1 x .125” 0.32cm and the other 0.5” 1.27cm. They suggest the soft foam squares give you the ideal cushioned work surface for shaping flowers, leaves and other fondant and gum paste shapes. Use thin squares for thinning petal edges with a ball tool. The Center hole in one square is perfect for wired flowers. Use the thick square for cupping flower centres and imprinting vein lines on leaves. There are further care instructions on the box. They come brand new in the original box, but I did take them out to photograph as it was not sealed.
