Thank you for viewing. I opened the package once to check for cracks or damage, but it is new and unused. Although it is new, there are some slight paint unevenness from the beginning. This is a set of 6 Christmas ornaments, each with a diameter of approximately 15cm. They are not made of glass. Hooks are included. Because the ornaments are large, I think they are impactful and very cute. I will pack them with care, but I cannot be held responsible if they break. Please understand this before purchasing. Thank you very much. COSTCO
