¡Hola Bellas! When you apply your false lashes, you are going to need: lash glue, tweezers, and of course the lashes. If they are new, you are going to need something to trim them. So, you need to trim your lashes so that they fit your specific eye shape. When you cut it, only cut the end, not the beginning of the lash. To glue them on, get your lash glue and apply it all on the strip. Don't apply it right away, you have to wait for the glue to get tacky. When the glue is tacky, it's more sticky and it applies faster. You'll know when it's tacky when the glue starts to dry clear, but not fully clear. Then apply the lash with your tweezers to the middle of your lash line, then apply it to the corners of your eye using the tweezers. Now you're done!!
