This Review Title is Try this trick to easily use this great floss. and the content is: Have trouble holding this great floss? Try this: cut a piece about 14 inches long. Double it over then tie a simple overhand knot four to five inches down to form a loop slightly wider than your hand. Gently try to floss a tooth. Adjust the knot to an ideal size for you. The magic is that the knot is easily moved by separately pulling the ends. Once it's optimal tie a second knot and tease it until it sits on the first knot. They will now be locked into position. You can apply loads of force without deforming your loop..There are other information for this review, one is This reviewer did purchase it and the other is 2 people think this review is helpful.
