My family situation has changed, and I no longer have any use for this. I've used it about 10 times. There is blackening typical of aluminum pots. I believe the lid's pot holders have been replaced. I don't see any dents, but there is dullness and blackening. Please consider purchasing only if you understand that this is a used item. The step size is 21 cm, and the outer diameter is 22.5 cm. I will wrap it in bubble wrap and ship it in a bag.
