I ended up purchasing more of these appliques after my initial pack in my Birchbox. These are really great for someone like me who doesn't always feel like waiting for polish to dry. I also love the fact that they come in so many colors & options - I have always received compliments on my manicures with these!
The only downsides are that they are tricky to remove, even though you can take them off with regular polish remover. They also are a bit harsh on your nails if you use them more than 1x/month or so.
