These are vintage Ultraman series monster erasers released by companies like Popy in the 1970s. There might be one or two items from other series, and some may not have imprints, but most are authentic with imprints. They are old, so there are scratches and stains. Some duplicates and damaged items are included, so they are being sold as junk items. Everything is shown in the photos. There are about 150 pieces. Please allow for some minor discrepancies. Please consider the photos when making your purchase. Thank you.
