the frosting and they are very sturdy. we also love the pink color. i definitely recommend them.
these boxes are not only pretty, but they are sturdy as well-made. the only downside is that they are pretty small, but that is my own fault because i should have measured. they could easily fit two cupcakes, but if you pile the frosting high the box would not close. i plan to buy more pink boxes in a larger size along with some inserts too.
