I won these as prizes at a game center. There are two sizes; the larger ones are 2 pieces, approximately 59 cm wide, and the smaller ones are 8 pieces, approximately 53 cm wide. They are unopened since I got them, so the vertical length is unknown. Are there any takers? Although they are unopened, please refrain from purchasing if you are looking for a perfect item or are overly concerned about condition, as they have been stored by a private individual. Please purchase only if you understand.
