To use these VLash J Curl lashes, first pick the right length for your eyes. Apply a small amount of lash glue on the lash band and wait for it to get a bit sticky. Then, carefully place the lashes as close to your lash line as possible. You can use them as a full set or mix different lengths for a more customized look. When it comes to maintenance, be gentle when removing them. Don't tug too hard as it might damage the lashes. After use, clean them with a mild lash cleaner and store them in a dry and safe place. Also, make sure to keep the glue away from your eyes. If you feel any discomfort, stop using the lashes right away.
