Instructions: 1. Remove the blue protective cover and use the dental floss directly to remove foreign matter from the mouth. 2.The handle is long enough to remove food residue deep in the teeth. 3. After using the floss, find the floss head at the handle, then remove it counterclockwise, and wrap it around the side cutting blade to cut off the used floss. Pull out the same length of floss and straighten it according to the original path. Then cover the protective cover. 4. If the dental floss is used up, please replace it with a floss that is less than 30 meters in length to avoid not being able to fit in.
