This is a set of Shigeo Nagashima's PET bottle caps. I received these as a gift, and they weren't stored in a case or anything, so the surface was black. I cleaned them up considerably with disinfectant wipes, but there is still some slight blackening. Please understand this before purchasing. Instant purchase is welcome. Shipping is planned via Takkyubin Compact. #ShigeoNagashima #Mr. #ProfessionalBaseball #YomiuriGiants
