I would hold fire shaving with these, they are labelled as Industrial { any serial numbers } Check out your source,and liase with other US Shavers.Got the blades in today. First shave tomorrow morning View attachment 588984
Suggest you get small pack from one of US Pharmacy Chains.
CORRECTION
It would appear that they may be OK if info on previous post is OK, Article re razor blades & More, shows serial numbers of Blade Packs which are Ok For Shaving.
