These boxes are the signature for my little cake business. I have used them (in all their iterations) for about five years. When people see the black box at an auction, or delivered to a restaurant, they know that Shellye's Kitchen is the source. I couldn't be more pleased. They work whether the cake has no icing (i.e. lemon or vanilla pound) or has chocolate, coconut, caramel, or German Chocolate icing. Nothing sticks and being able to close the box without touching the cake is an added wonder element. They make a wonderful foundation for a great presentation. I love them!!!!!
