This is such a want, I know these haven't been out for too long so I thought I would show everyone these new 17 nail polishes.
Basically they are these magnetized polishes, you coat your nails once in the polish then you use the lid ( which is the magnetized bit ) against your nails and it pushes and moulds a new colour/decoration on your nails which then comes up looking like the picture above. I got the picture off google images btw but i wish they were on my hands!
They also come in the colours : Gun Metal, Lilac, Blue and Teal. My favourite has got to be Lilac. I know other nail polish brands do this as well like nails inc. they only cost £5.99 which isn't too bad but apparently it chips within the first three days but hopefully they are worth my money because I am getting a bottle.
