This kit is everything you need to get started with Lashies Lash Clusters. I love the Jazzie clusters. I followed the tips from a review video suggesting that you rotate back and forth between sizes. So I started with 16 mm cluster at the outer corner of my eyes, then overlapped the edge with a 14 mm cluster, then 16 mm, then 14 mm, then 12 mm. I overlapped the edges. I am very pleased with the look. For a more natural look, I've done 12 and 10 mm on my eyes, too. Using the 16, 14, and 12 mm together creates a more dramatic look. You can see that in the photos for this review. I feel beautiful when wearing these lash clusters, and getting ready to go out is so much faster when wearing them. I just throw on some foundation, highlighter, blush, and setting powder. Nothing else needed on my eyes. I actually feel already put together first thing in the morning, even without makeup. I've showered while wearing them--face fully in the water--and they came through great! Just don't rub your eyes. The longest I've worn them is 6 days. When putting them on, I recommend that you trim the little plastic edges off on the clusters you place on the outer corner of your eyes and inner corners of your eyes so the edges don't irritate your eyes. If you're on the fence, don't delay any longer. These are great.
