Operation has been confirmed. The battery's level of depletion is unknown, but it has not been stored in a cold place. All included accessories are shown in the images. Some attachments are unused. I disassembled and washed it with water, removing any debris, but please be aware that there may be some remaining dirt that couldn't be removed. The model name display on the stick has peeled off. Also, there are no pets, so there shouldn't be any issues regarding cat-related allergies. This item is sold as-is, so returns are not accepted. Please be aware of this when purchasing. Due to being a precision instrument, there is a possibility of malfunctions during shipping, but please understand this before purchasing. Thank you for your consideration.
