Thank you for viewing. This is a Casio IS-N1000, released in 2005, containing the Igakushoin "Nursing Dictionary / Medical English-Japanese Dictionary / Drug Therapy Manual." It's an older item, but it has an SD card slot, so it might be expandable. Although there are no booklets, you can download the instruction manual from the internet. It contains 6 medical books and 7 language books, so you can use it as a regular dictionary. There are minor signs of use, small scratches, and dirt, but the operation has been confirmed. It comes with batteries for testing, so you can use it right away. The items in the images are all that are included, and there are no other accessories. Please understand that this is a used item before purchasing. It will be protected with cushioning material and shipped via Yu-Packet.
