Using these lashes is easy. First, clean your natural lashes gently to remove any dirt or oil. Then, pick up a lash with tweezers and apply a small amount of lash glue to the base. Wait a few seconds for the glue to become tacky, then carefully place the lash as close to your natural lash line as possible. For best results, start from the inner corner and work your way out. When you're done, you can gently press the lashes to make sure they're well - attached. As for maintenance, avoid rubbing your eyes vigorously. If you want to reuse the lashes, remove them carefully after use, clean off the old glue, and store them in a lash case. And remember, don't expose them to excessive heat or moisture.
