Approximately 27cm in length and width, and approximately 2cm in height. Although it is unused, there is a slight scratch when viewed diagonally. No box included. As a measure to prevent breakage, I will wrap it in bubble wrap and place it in a cardboard box. I will also request the black cat Yamato delivery service to put a fragile sticker on it and raise the bottom of the box. Regarding any damage or other issues, I will handle them through the Mercari administration. No price reduction is possible. Although it is a new, unused item, please understand that it is not perfect due to home storage, and I ask that you refrain from giving a negative evaluation. Returns are not accepted. I am also listing this item on other sites, so it may be removed suddenly.
