Diameter approximately 15.5cm, height approximately 5cm. There are black spots that appear to have occurred during manufacturing. Price is not negotiable. As a measure to prevent breakage, I will wrap the item in bubble wrap and place it in a cardboard box. I will also request the black cat Yamato delivery service to apply a fragile sticker and provide bottom cushioning. For any issues such as damage, I will handle them through the Mercari administration. I ask that you fully understand that this is a used item and that you will not leave a negative review. Returns are not accepted. I may suddenly delete the listing as I am also selling on other sites.
