I received this pen free for my honest review on Amazon. The pen comes with 4 tips. I personally saw no difference in the tips. The pen comes with no acetone inside. It can be easily filled by removing the tip and pouring the acetone in. I find that a bit messy, so I prefer to just dip the tip in acetone as I’m doing the cleanup of my manicure. Over all, I like the design and colors and it does what it was intended to do. 
Beauty Tips for Women: H&M Heaven Sent Nail Colour Trio Manicure
I recently posted about the deal I got on a nail polish trio set from H&M called Heaven Sent. I did a manicure using all three: Space Race (holo polish), Prismatic, and Neo Noir. Two coats of Space Race with no formula issues. I love the holographic effect Space Race has. For the accent finger I used two coats of Neo Noir. Neo Noir was a bit runny which was the only negative about the trio set. A lovely trio, that if you can find it, you should get.
