I absolutely love love love this product, it's really easy to use it does have a guide with it but basically you paint your nail then pour the balls onto the desired nail but when I did it, I did I over a bowl so I could pour the little balls back in!
You can get different colours, see little gem blog for other ideas!
And they stay on really well, especially if you put a coat of clear nail varnish over the top!
I think my nail looks like a nobbly bobbly! Love that x
