The CASIO FX-3600P is a silver calculator with function calculation capabilities, and comes with a cover. Purchased in 1982. Includes instruction manual and box (both are quite damaged). Only checked for basic arithmetic operations. Secured with tape in four places. A Monchhichi sticker is attached to the cover. I took the photos with a new battery installed. I will remove it and include it. Please refrain from claims or returns after purchase. Thank you for viewing.
