The manufacturer is unknown, but it is likely a felt pin shoe made by a domestic manufacturer as it has the Japan Fishing Tackle Manufacturers Association mark on the box. The size is free size, but it is probably around 24cm. It is a new and unused item, but it is an old one. Due to long-term storage, there are slight stains. As far as we have inspected, there are no peeling of spikes or rubber, but it will be sold as-is. The box has scratches and writing on it.
