I purchased this for studying bookkeeping and accounting at school, and although I opened the package, I ended up using a calculator I already had, so I never used this one. The box and instructions are not included, but it is unused. There is a possibility that the warranty will not be applicable if you need repairs, but I would be happy if someone could use it. I have a cat. I am careful, but there may be some cat hair on the item. Please be aware of this. This item is stored at home, so please purchase it with the understanding that it is a used item. Please check the images for details. I plan to ship via Rakuraku Mercari. I generally try to ship within 3 days of purchase. I check the item when listing it, but there may be minor scratches that I am unaware of, so please purchase with this in mind.
