I was introduced to this product a few years ago by a very close friend friend of mine. At first it seemed insiginificant like every other beauty product out there, it showed no particular difference. When she explained how great the product was to me I thought it was just her way of exaggerating things again. A few days later I notice there was something different about this friend, her eyes seemed smokier then I noticed it was the eyelash curler that did the trick. A few weeks later I took her advice and started using this product. Its been almost two years now my eyelash is never the same and the curler is just as new and usable as I first bought them. The price of this product is great, and usually the rubber piece of eye lash curlers gets loose or have a cut in them due to the long term usage but Shu Uemura provides something magical the rubber piece never gets old and it provides extreme comfort. This product really does worth every penny.
