I sent two pairs of tweezers into Tweezerman for the "free" sharpening. They were sent in a padded envelope through USPS. I kept the receipt. I filled out the form on the Tweezerman site and included all information as they asked,. They say give us your email address so you can follow the progress of your tweezer sharpening. Never heard from them again! Tracked package back through USPS and it was successfully delivered to their mailroom on a date I have and the exact time. I sent a letter with the postal receipt to them telling them about this. They never opened the letter! They sent it back to me in a padded envelope saying it was damaged but it was in its original state that I had mailed it to them in! Something is really wrong here. I will never buy a pair of their tweezers again! Do not spend your money on these tweezers and if you already have a pair do not bother sending them to Tweezerman for sharpening because you will most likely never see them again. If I could give them no stars I would!
