Our size L double eyelid tape set contains organic silicone PET film and high-quality fibers. It is natural-looking, long-lasting, convenient, quick to use, and waterproof and sweatproof. It's easy to use: spray water around the eyes, the tape adheres when wet, then use the Y-shaped fork to remove the double eyelid tape and apply it to the recessed area of the eyelid. Use the Y-shaped end and the other end to adjust the position of the eyelid tape. Once adjusted, you can blink and the tape will stay in place. It also makes your eyes look more expressive
