I have had some blue wrapped Personnas for some time now. I'm not sure if they are the same blade as the 250 pack, especially if I recall someone mentioned that the medical blades come in the same wrapper.
When I first used them I thought they were great blades. Then I put them away and went back to them later. Then I thought they were pretty dull. Problem is that I don't remember which razor in which I first used them and I think the razor and blade combination is really what makes a blade sine or fail.
Nick Rivers: Hillary. That's an unusual name.
Hillary Flammond: It's a German name. It means 'she whose bosoms defy gravity'.
Nick Rivers: I'm pleased to meet you. My name's Nick.
Hillary Flammond: Nick? What does that mean?
Nick Rivers: Oh, nothing. My dad thought of it while he was shaving.
