Although the Tweezerman lashcomb has the most tiny, well defining lash separators, the plastic body is not durable. After a couple days, and a couple rounds of cleaning, the comb portion came out of the plastic. I super-glued it back in place, but after more use, the hinge broke. I don't know why it was so fragile. I hope that Tweezerman will upgrade this product so that it has the sturdiness I have come to love from their tweezers.
