I received the sealed package very promptly. Other reviews have stated the product is not genuine or appears to be out of date, but neither of those are true: I received genuine Neulash in a sealed box. I can't really rate the product itself yet, as I've only been using it for a few days. It causes some very minor itching, so it's definitely best used right before bed. I've had no irritation, but I consider the itching a hopeful sign - it's been my experience that the serums that work cause a slight itch as the follicles become more active.
