Chi. - About the Movement of the Earth - Earth (iwa) Moving Exhibition Limited Edition Acrylic Stand with Star Chart After opening, it was displayed in a dark place. With instruction manual. As shown in photo 5, the star chart has become slightly warped, so we recommend securing it with a clip. (⚠︎︎ I didn't use a clip when displaying it. I attached it for the photos!) If you need one, I can also include a clip, so please let me know in the comments. The clip is lightweight and won't leave any marks.
