This is probably a super rare miniature car of a Citroen DS. It's 5cm in actual size. The underside is engraved with "AHI BRAND TOYS JAPAN". After some research, it seems to be a rather rare item made by Kuramochi Shoten. If you miss this opportunity, it will likely be difficult to obtain, so how about it? However, please refrain from purchasing if you are overly concerned about details.
