※Also listed on other flea market apps ※Please note that this is a junk item and does not function properly. This is a set of two items released by Gakken in 1989: the "Pencil Calculator" and the "Tashikame Keisanki Dentaku Wanta" (Confirmation Calculator Wanta). These are unused items stored in a dark place at home, but they have been opened once for condition check. Due to long-term storage, there is overall signs of use, scratches, and discoloration. The box, in particular, shows noticeable warping and discoloration. Furthermore, when I checked the operation of the main unit, it would not turn on. It may function properly if you remove the lid secured by screws on the back of the unit and replace the batteries, but this has not been confirmed. Please be aware of this in advance. If you have any questions, please feel free to ask in the comments.
