Did I keep the box which these came in? Of course not! Do I wish I had? Definitely! If I still had the box, I would make good on the "lifetime warranty", as these tweezers have already chipped and become dull. I am really bummed because they were great upon purchase; incredibly sharp and great at grabbing even the tiniest baby hairs. Too bad they are useless now, and won't even grab long hairs. I could have sworn Birchbox dubbed these one of the best pairs of tweezers, but it appears that the other reviewers of this product share my sentiments. Back to my quest for the best pretty pluckers!
