This is a used item. I purchased it for an art class and used a few chips during the class. I stored it in the outer box inside a cardboard box. (See photos) It's old, so the box has yellowed due to aging. I haven't taken it out except for class, and I stored it in a dark place, so I think the contents are fine. Rakuraku Mercari delivery (anonymous shipping) 450 yen, seller pays shipping. The thickness is barely 5cm. I will ship it via Takkyubin Compact. It will be waterproofed with a freezer bag and bubble wrap only. I'm selling it to organize my belongings, so I will dispose of it at the end of November.
