#7 lashes are spiky, seperated (not that full) and they finished off that evening look yelling "GLAM!" Love the effect that it created. I didn't use the DUO adhesive that MAC offers but i don't think it matters... make sure to not over-apply the glue. It pulled my eyeshadow off into the lash at the outer corners of my eyes. because of that i ended up taking the lashes off and throwing them in my bag. the next day i was worried that i had misshappenned them. they were fine and lived through a makeup remover bath with the makeup out of the lashes and the band still sticky if i want to reuse them.
