These are vintage Ultraman series monster erasers released by companies like Popy in the Showa 50s (1975-1984). There might be a couple of items from other series, but the majority are from the Ultraman series. Some don't have imprints, but most are genuine with imprints. They are old, so there are scratches and stains. Some duplicates and damaged items are included, so this is being sold as a junk item. Everything in the photos is included. There are about 170 pieces. Please allow for some margin of error. Please consider purchasing based on the photos. Thank you.
