GSB. I've been trying a bunch of new blades and hit an appealing sharp/smooth sweet spot. Also, in country, free shipping, good price. I grabbed 50 Nacets too which seem almost as promising.
Ah, looks like you got some Lab Blues. They’re nice blades smooth and sharp. They were also my last 100 blade purchase.
If you see a Personna blade with the words “For Hospital Use”underneath the Personna label that will indicate that it’s a Med Prep. Yours are in the same kind of box and labeling as mine. They are very decent blades and only half the cost of the Med blades.
