Thank you for viewing! This is a Casio card-type thin calculator (SL-760LB). It's a slightly unusual black marble (brushstroke-like) design that is no longer sold. It's the size of a credit card and very thin, so it won't take up much space in a planner pocket, wallet, or chest pocket. 【Product Details】 ・Manufacturer: CASIO (Casio Computer Co., Ltd.) ・Model Number: SL-760LB BK ・Digits: 8 digits ・Size: Standard card size (ultra-thin) ・Power: Solar powered (can be used in bright places) 【Condition】 ・Operation check: Completed (No problems with number input or display. Please check the first photo) ・Appearance: There are no major cracks or noticeable stains, but please forgive any fine scratches that can be seen depending on the light, as this is a used item and has been stored at home. ・The printing on the back is also relatively clean. 【Shipping】 It will be placed in a waterproof bag and reinforced with cardboard before shipping. How about it as a sub-calculator for work or school, or for those looking for stationery with a focus on design? Instant purchase is welcome! #CASIO #Casio #Calculator #CardCalculator #ThinCalculator #RetroStationery #Compact #SL760LB
