Exactly so.I believe the Personna Lab Blues are also know as the Personna Comfort Coated (in a blue box with 100 blades), is that correct? If so, I like these in almost any razor I own or have ever owned.
I don’t know why forumites call them Lab Blues. They are almost the only Personna blade that doesn’t come in a blue box and they don’t say “Lab” anywhere.
