Thanks a million. These are so nice I think they have some nylon or polyester in them something synthetic because they just last and last. These are F L A T! That is the whole key and the weaving that makes them even strengthens them. I have looked all over the place to find flat shoe laces. I have so much trouble finding them. You have them. These are Made in the U.S.A. Fantastic. That means alot to me too. I have the little box with the address and company data taped in my Rolodex. Dave from Milwaukee
