A good 2 to 3 years since I only shave a couple times a week.
So a slight tangent....blades are what concern me most for long term. I'd like to buy up, but I'm concerned about corrosion. What do you folks think about long term storage for blades? My goto blades are feathers, and they do come in the plastic case with clear plastic wrappers on each one. I currently just store them in a box with a handful of dessicant packs. If I buy a huge stock though, I'm thinking about vacuum sealing them. Helpful? Necessary?
x2. At least.Blades, soaps & creams, aftershaves - probably around 10 years of each.
