    Perfff

    I love this stuff so easy to application. Remove and maintain. It takes some time and patience. And a lot of practice but once you get in the flow of things you are away. I'm always getting compliments for my nails and this color. People cant believe I do them myself! And they are FINALLY my own nails, not acrylic tips! 😅 💅 my nails are always on fleeeeeek and I ain't mad, heyyyy. Let's goooooo queens

    Love the sparkle!

    I love both the colour and glitter in this one. I put multiple layers to get a darker colour.
