I've been using the store brand blade for 10 years. I read on here back then that more than likely store brands are Personna blades. I accepted that. I had no reason to doubt the shaving pros on B&B. (I was the ignorant newbie; who was I to contradict? Now, I'm the ignorant decader.) I was in the grocery store today and looked at the package, and they said made in Vietnam. So I did a search here, and apparently that would make them Dorcos. Various posts I saw said if it's made in Vietnam, they're Dorco.
