I do my best to do same day, if not next day service to get orders out my door quickly. Therefore, I provide a service and then the post office takes over after that. This edible image cake topper is a thin frosting sheet that will fit a quarter sheet cake. (print area 7.5? x 10.5") Apply directly to the buttercream iced cake. Allow an hour or more to melt into the buttercream (May have to dab the buttercream to moisten before applying the topper) SAVE the personalized message in note to seller or I won't see the info you request. As long as the sheet is stored properly, it will last a couple months. Ingredients: Available upon request. This listing is for GRAPHICS EDITING SERVICES ONLY.
