They're £7.99 per set and there are 3 sets available in Boots. (I believe there is another set you can get on the skin art website also which has styles which are like celebrities). These are called, "I'm a dreamer", "Love is enough" and "In your own words".
All three sets are nice, but I decided to try the "Love is enough" set.
The set can be seen below.
I've only tried two tattoos so far and they looked really nice and I got compliments from people about them. Not one person thought the were only temp! They lasted about 3 days without scrubbing where the tattoo was, which isn't bad considering.
Here are two pictures of the ones that I have tried.
I hope this review was informative!
