SHARP EL-5103 Scientific Calculator ★ This is a scientific calculator, the EL-5103, made by Sharp. It's missing batteries, so its functionality is unknown. (It requires three LR44 button batteries, but they are not included.) ★ Since I haven't been able to confirm its operation, I'm selling it as a junk item. ★ Please understand that this item has been stored for a long time before purchasing. ★ The main body has some minor stains. Please check the photos. ★ Please refrain from purchasing if you are sensitive to imperfections or seek a perfect item, as this is a junk item.
