Ultraman Zero Role-Playing Cap Zero Slugger is detachable. I think it was around 3500 yen at the Rakuten Ultra Shop. I didn't like the size tag showing through the mesh part, so I removed it, but it said 54cm. For reference, the size adjustment belt in the 11th photo is about 51-52cm. I liked wearing it, so there is a feeling of use. The size adjustment belt has scratches. It will be shipped via Yu-Packet.
