Yamanashi 24 Kanagawa 24 Nagano 26 The numbers likely represent years. It's probably Heisei era, but the details are unknown. m(_ _)m Please refrain from purchasing if you are sensitive to minor scratches or slight stains. These are not pin badges, so they won't fit unless the hole is a bit larger. If you want to use thread or string, there are holes at the top and bottom, or left and right, so you can thread them through and secure them. I think it would be nice to enjoy them as antique or vintage collectibles(^^) Feel free to ask any questions♪
