Using the Ardell Wispies™ 704 false lashes is easy. First, make sure your natural lashes are clean and dry. Apply a thin layer of lash glue to the Invisband® lash band. Wait a few seconds for the glue to become tacky. Then, carefully place the lashes as close to your lash line as possible. Start from the inner corner of your eye and gently press the lashes down. For the best fit, you can trim the lashes to match the width of your eyes before applying. When it comes to maintenance, after each use, gently remove any remaining glue from the lash band. Store the lashes in their original case to keep them in good shape. As for precautions, avoid getting water or oil on the lashes when they're on your eyes, as this can cause them to lose their hold. Also, if you have sensitive eyes, it's a good idea to do a patch test with the lash glue first.
