Thank you for viewing. This is a Maku-cha Collection Board sold by Nagoya Railroad. It appears to be made of styrofoam, with hook parts to display keychains. The back of the main body has a stand, seemingly made of paper, that can be unfolded. Although unopened, there are some dents on the side as shown in images 3 and 4. Size: Approximately 250*450*8mm It will be shipped in cardboard or a packing bag.
