This is a non-sale coin-shaped charm featuring a rabbit and cherry blossoms, which was included only in the lucky bags of Kasou Koubou in 2011. It has been stored unopened since the initial packaging. Although there are some signs of oxidation due to aging, it is silver, so it should become beautiful with polishing. I will send it as it is, unopened. Diameter: Approximately 22mm, Inner diameter: Approximately 4mm, Thickness: Approximately 3mm Weight: 11.7g Measurements are approximate. I believe it is silver, but there is no hallmark. Please consider purchasing if you understand the current condition.
