I have had this set of Sally Hansen Salon Effects Real Nail Polish Strips since before Halloween last year. When they were released for a limited time. The design is called Spun For You and it a pretty silver background with a black spiderweb pattern.
I love the Salon Effects, they are very easy to apply and I find they last at least a week before I remove them. Usually I remove them because I have grown bored of the pattern :)
If you haven't tried these yet I suggest you get to your local stockist and try them out!
