I previously purchased this item through crowdfunding. The ALL7 portable fan is a necklace-type fan that can be used on the face, neck, inside clothing, and as a desktop fan. The main unit can also rotate 180° vertically, and the wind speed can be adjusted in 3 stages to control the direction of the airflow. There are no noticeable stains or scratches. It has been cleaned with alcohol, but please refrain from purchasing if you are sensitive to used items. - Model Name: ALL 7 - Type: Neckband Fan - Power Supply: USB Charging - Wind Speed Settings: 3 levels - Included Accessories: Instruction manual, USB cable Thank you.
