          My Favorite! 😍

          This is the only Lip Oil I’ve ever finished before!!! It’s that good. It was the smaller one in the shade Jellyfish but I still used it all the time. I have it in multiple shades though. It’s so beautiful, at the same time it feels great and moisturizes my lips. I have the shades Malibu, Exposed and Unhooked. When I had Jellyfish I kept it right in my nightstand drawer. I can’t reccomend these enough! I need more shades. You can dress them up or wear them whenever. Definitely can be worn on their own or over lipstick. These are a must! 😍😍😍

          Perfect and I mean perfect

          This lipgloss is not sticky and has just the right amount of shine.It has great coverage, but not too much and it has long lasting wear. I cannot say enough about this product!
