Based on our own experience, these cardboard circles are perfect for baking and decorating large cakes .They are sturdy and can hold up against heavy frosting and decorations. The circles are also easily disposable, making clean up a breeze. The only downside is that they come in a larger size, which may not be suitable for smaller cakes. Overall, a great purchase for any industrial and scientific baker looking for a reliable solution for their food service disposables..See full review
