1x Edible Wafer Paper Cake Topper. The wafer topper can be used on dry toppings (marzipan, fondant, chocolate or icing). Spread the icing very thinly on the cake where the topper will be placed, wait for it to be nearly dry (sticky), then place the topper on top of the icing and press very gently smoothing the topper from the centre to the edges.
