This is an authentic CASIO SL-110 Solar Calculator, a compact folding-type model from the Showa era (1980s). Equipped with a high-power solar cell, it operates without batteries and features a 10-digit display. Its practical yet refined design won the Good Design Award in 1984, showcasing CASIO’s innovation during Japan’s golden age of consumer electronics. Operation has been confirmed — all basic functions such as calculation, GT (Grand Total), AC/C, and memory operations work properly. As a vintage item, there are small scratches and signs of wear consistent with age, but overall it remains in good, functional condition. An ideal collectible for retro technology enthusiasts, Showa-era memorabilia collectors, or those appreciating Japanese industrial design.
