PH-balanced, non-toxic adhesive - safe to use. Plastic tube - easy to use. High-quality cosmetic eyelash glue - comfortable and long-lasting. Good waterproof adhesive. Apply a thin layer to the base of the false eyelashes. Leave it on for 25-30 seconds or until it becomes tacky. Place the false eyelashes close to the base of your natural eyelashes and press firmly until the adhesive dries.
