PIKO G Buildings and Accessories are made primarily of an extremely tough, UV- and weather-resistant polycarbonate plastic material, with ultra fade-resistant color molded in. Many parts are also lightly weathered for a more realistic look..
Most kits include a tube of plastic glue, for buildings that will be used indoors. For outdoor use, we highly recommend using PIKO #55701 PIKO-Fix plastic cement to truly fuse the parts together.
