Nostalgic Showa era erasers: Sumo wrestlers (8) and professional wrestlers (7). I remember buying these from gachapon machines in the 1980s. I've used these for a long time, so there's dirt and stains. Especially the yellow ones are darkened. If anyone can clean them up, please consider purchasing them. #51 # Sumo # Sumo Wrestling # Professional Wrestling # Mil Mascaras
