I am selling these items because they are from a collection and I won't be using them. A set of three types of baking cups. - Sizes: No. 11, No. 5 (aluminum, pink) One No. 11 cup is unopened (500 sheets) x 1, one is opened. No. 5 aluminum is unopened (500 sheets) x 3. No. 5 pink is opened. 1 set contains 500 sheets. The opened ones have less than 500, but most are remaining.
