You can now choose between a ceramic or MDF ornament (medium density fiberboard) material. Ceramic ornaments can be fragile and heavier than the MDF, as they are ceramic. MDF ornaments are lightweight and stiff, not easy to break or deform, and safe and reliable. They are approximately 3in and 0.12in thick. Ceramic ornaments come with a gold string, and MDF ornaments come with a red ribbon.
