I picked this up up when it was on sale online in the shade magnetized which is a lovely fuchsia pink shade, just to try out the magnet nail effect for myself. Unfortunately I didn't find this very easy to use and found the design of the polish and magnet poor. My magnet fell out of the lid after the first use and due to the design and placement of the magnet I found it hard to get an even effect on each nail...however, I did really like the star effect that the magnet gave my nails.
In terms of the actual polish it didn't last long on me before chipping (I had chips by the second day) and I got bored of the effect pretty fast. I think this would be a neat gift for a younger lady, but, it's not something I would try again.
I picked this nail polish up for $5 on sale and I'm impressed. I have the pink/fuschia one and I love the colour. It has a nice thick consistency so you only need to use one coat. The magnet needs to be used after you've painted each nail individually as the nail polish is so fast drying. the colours are so shimmery and the magnet gives such an awesome effect.
