Easily imprint interchangeable scroll designs on buttercream or fondant cakes using this 19-piece set. Also works great with cookie dough. To use: Slide tile pieces on to the holder in the desired design, and slide the flip locks on either side to secure tiles on the holder. With very light pressure, press design onto the side or top of cake to leave a slight impression. With a decorating bag and desired top, pipe over design. When using buttercream, let the icing crust 15 to 20 minutes to make imprinting easier.
