National Panac 364 (JE-364) Solar-Powered Genuine Leather Calculator This is a vintage folding pocket calculator manufactured by Matsushita Communication Industrial (now Panasonic). This product, which heralded the innovative "Third Calculator Revolution: From Hard to Soft" at the time, was the industry's first model to feature genuine leather. Key Features: Brand/Model Name: National Panac 364, Model Number JE-364. Power Source: Equipped with a solar battery (solar cell) and operates with light. Design: A folding type designed for ease of use and portability. Material: Uses genuine leather for the main body, as indicated by "Le Cuir (Genuine Leather)". Original Price: Standard price was 7,500 yen. Year of Manufacture: A vintage item likely released in the mid-1970s. This calculator is currently traded as a collector's item mainly on online marketplaces such as eBay. AI Mode I believe this is remaining stock from a store I used to run, so it's likely new and unused. It has been stored in a camera dehumidifying cabinet, so the condition is good and very clean for its age. It responds immediately when opened, and the power indicator lights up. Operation has been confirmed without any problems; it's in good condition.
