Thank you for viewing! This is a DOSHISHA slim compact fan, a tabletop fan/circulator. It has been stored at home, but I am selling it to organize my belongings as it has been used infrequently. Operation has been confirmed. Please check the condition in the images. Batteries are not included. It can be used with a household outlet/USB/AA batteries. It can be used both indoors and outdoors, in places like an office desk, kitchen, or toilet. It has two wind speed settings. How about it for heatstroke prevention? For those who understand that this is a used item, please consider purchasing with no returns or claims. It will be shipped via Mercari delivery service.
