This handy fan has three speed settings. - Model Name: SMART 3WAY FAN - Size: Approximately 2.5 x 7 x 14.3 cm - Usage: Desktop, handheld, neck-worn - Power: 2 AA alkaline batteries (sold separately) - Fan Speed Settings: 3 levels It can be used continuously for 8 hours. Since it's battery-powered, I think it would be useful in a disaster. It will be shipped in its original box, wrapped in paper. I am also selling the same item, so if you need one, I will add it for an additional 500 yen.
