Sharp PW-9910 electronic dictionary. Uses AAA batteries. I hadn't used it for a long time, so I put batteries in to check its operation, and it worked without any problems. Please research the product details yourself using the model number, etc. I cannot answer detailed questions. Since it has been used, there are some minor scratches here and there, but it seems to be in good working order. If you wish, I will include the batteries I used for the check, but please consider them as a bonus as I don't know how much charge they have left. I carefully inspect the items and try to communicate any concerns through text or photos, but this is a private seller selling items stored by a non-professional. Please check the photos carefully beforehand and make your purchase only if you are satisfied. Regarding the size, I try to take photos with a measuring tape, but please forgive any slight errors as it is a rough measurement. Returns are generally not accepted after purchase, so please check the photos and comments carefully beforehand. Shipping will be via Mercari shipping. The carrier may be changed to either Japan Post or Yamato at my convenience. To reduce shipping costs, I will pack the item as small as possible while still protecting it. For packaging, I often reuse materials if they are in good condition. When packing, I may use newspaper to fill gaps for items that move around. Some people have complained about this, but I hope you understand that it's better than the item being damaged. Thank you for your interest.
