One blade in a Gillette multi blades lasting a month? That’s probably not accurate. Although I think mine is likely more than ten years old and it’s still brand new, and as long as I never shave with it I won’t have any irritation.
Good point. I can honestly say I have had zero irritation from a multi-blade razor since, oh, 2010 or so...
It was in original condition, faded red, well-worn, but nice.
This was and still is my favorite combination; beautiful, original, and worn.
