I recently bought a box of the Sally Hansen salon effects, you know, the little nail polish strips you peel off and stick on your nails? I've actually purchased them before this and they didn't work well, but I decided to give them the benefit of the doubt and give it another go.
so I bought Frock Star, and followed the directions exactly, and the same thing happened, they only kind of stick, the rest of them peel off and in about two days they were falling off left and right.
so I sent them an email and they said they'd send a replacement.
today I got an envelope with a bottle of their gem crush nail polish in a glittery pink color, a bottle of clear top and base coat and a sample of a Roberto Cavalli fragrance.
I'm not sure why they sent me something completely different than what I bought in the first place, but it's nice none the less.
my sister in law actually had the same problem and they sent her a replacement of the item she bought originally.
so if you've had any problems with their products, I believe they're willing to send out replacements.
