I'm selling a nostalgic Sharp card calculator. Since I haven't replaced the batteries, it's a junk item. I don't remember the exact year, but I think it's from the end of the Showa era or the beginning of the Heisei era. It was a time when card sizes were popular, so it was a cutting-edge product at the time. Size: 85 x 54 x 4mm Sharp Practical Calculator, Handheld Type EL-WA10-X Brand: SHARP
