Haikyu!! probably not-for-sale goods. It's a mascot strap with a Koedarize design of Kageyama-kun. My memory is vague, but I think it was distributed as a purchase bonus exclusively at 7-Eleven in the 2010s. It's unopened, unused, and has been stored in a dark place. Although it's unused, it's been stored by a private individual, so please consider purchasing only if you understand the condition, including initial scratches. Instant purchase welcome. Bundling welcome. If you wish to purchase individually or would like a discount, please consult via comments. Even during negotiations or a dedicated listing, the person who completes the instant purchase procedure will be given priority. If it has been more than a month since the item was listed, please check the stock in the comment section.
