Black eyelashes. HOW TO USE Align the lash band with your natural lash line to verify the fit. Trim the outer end if necessary. Apply a thin line of eyelash adhesive to the lash band and wait 30 seconds until the adhesive becomes sticky. Place the lash band as close to your natural lash line as possible and gently press down to secure it. To remove it, simply remove the tab from the outer edge and carefully remove the adhesive from the band to use it again.
