Dear sirs, i have a feather artist club dx razor and also an att kronos. Next days ill gonto europe for business trip and i plan to stock razor blades for artist club and also some double edge. i plan to make a stock for 20-25 years. if not opened these de and feather ac club blades will last for 25-30 years? Or they have an expiry date?
I really doubt a blade will have an expiration date since it's made of metal. However, I would make sure that when I store them I would put in some desiccant packets to make sure no moisture gets to the blades and possibly cause corrosion.
