But it would be interesting if these were in fact the exact same blade, off the same production run & line, one just stamped differently to another & packaged differently & yet another given a further sterilisation process.
I'm not trying to slight you & others who clearly think the Labs are a different blade to the Barbers, but the placebo effect is a very well known, common & proven phenomena....
As I say, I was very impressed with the Barber white dispenser blades & now prefer them to the platinum chromes which I also like a lot.
I agree placebo affect is real I've been in the medical field for over 28 years. But before I even read any of this and thought my white container Personna's were lab blues I never got 5 good shaves and shave 4 was ok. With the Blue Wrapper Labs I got 7 great shaves and I'm on 6 with the Med preps.
