I ordered a pair of lashes and the Hello KittyBlack magnetic eyeliner. I'm new to using magnetic eyelashes and I had problems with the eyelashes staying on. I received an eyeliner that must have been defective because I did everything as instructed, but they just wouldn't stick. I contacted customer service to find out what I'm doing wrong and the representative said it was the eyeliner and that Glamnetic would send a replacement and if I'm still having problems once I receive the new liner to contact them. The agent was very knowledgeable and extremely helpful. It was a very good experience dealing with Glamnetic and I highly recommend their lashes and eyeliner. I've had no issues once I used the replacement. Great customer service!
