The overlay is not smooth and it's very uneven, also my nails weren't painted nicely; very tacky, but the woman doing my nails was very lovely. It took about 2 hours 15 mins to finish, but overall since I only paid £6 due to promotions from birch box. And I would say it was good value for the £6 but if I paid the original price of £16/£20 I would be very disappointed. Great customer service though.
