This is a collaboration kung fu bat with the Hiroshima Toyo Carp, sold as a venue-exclusive official good at the "Okuda Tamio Hitori Matatabi Special @ Mazda Stadium" held in 2015. I purchased it at the venue and used it at the stadium that day, and have since kept it carefully as part of my collection. There are no noticeable stains, but there may be some aging. Please check the photos. Also, as it has been stored for a long time by a private individual, please refrain from purchasing if you are looking for a perfect item. Please consider purchasing if you understand that this is a used item.
