Using this double - sided fashion tape is easy. First, decide where you want to use it. If you're sticking two pieces of clothing together, just peel off the backing from one side of the tape and press it firmly on one garment. Then, peel the other backing and attach the second piece of clothing. If you're applying it to your body, clean and dry the area first, then stick the tape on gently. As for precautions, it's hypoallergenic, but if you see redness on your skin, stop using it immediately. Don't put it on infected or irritated skin. To maintain the tape's stickiness, keep it in a cool and dry place. Avoid exposing it to direct sunlight or high humidity, as this can reduce its adhesive power.
