This is a set of two jumbo block trailers, a Showa-retro toy. The material is plastic. The cargo consists of blocks that can be assembled for play, but unfortunately, one blue block is missing (see photo 9). The size is approximately 33 cm long, 7.5 cm wide, and 10 cm high with the blocks loaded. Although it is a new, unused item, it has been in storage for a long time, so please purchase only if you are not concerned about the photos. #ShowaRetro #ShowaRetroToys #Trailer #Blocks #NewUnused #Truck #RetroToys #AntiqueToys #VintageToys #TruckToys #TrailerToys #RareItem #RetroGoods #AntiqueGoods
