This is an 18cm cake pan. The bottom is removable. 18cm diameter cake pan Height: Approximately 6.5-7cm (Images are included.) It has been used a few times, but there are some scratches and stains that cannot be removed from storage, so please purchase only if you don't mind. A pack of 5 baking sheets (17cm) will be included as a bonus, making it a great deal! Thank you.
