To apply a cake topper to the cake, we recommend that you first clean and dry the cake to ensure that the cake topper adheres well. Then you can carefully remove the cake topper from the backing film and apply it to the cake. Use as little pressure as possible when doing this to ensure that the cake topper does not get damaged. If you have any questions about the technique of applying cake toppers, don't hesitate to contact us. We are here to help you and will be happy to assist you.
