I was actually scared to use this! I love the overall effect though even though i did mess up on one nail as i didn't apply it right.
I used Barry M Nail Paint in 273 Raspberry underneath and then quite obviously the Barry M 311 Nail Effect over the top.
As you can see on my index finger,it didn't apply very well but it doesn't look really bad.
I applied a top coat - Beauty UK in Clear however it was matte before I applied it and I kind of liked it. I may leave it next time,we'll see!
I love it:)
