I bought this razor and a pack of 10 blades the first week we moved to Zurich. That was three years ago. I only bought 10 because they cost something like 40 CHF. Which is outrageous. But a) I don’t shave a whole lot and b) these are some durable blades. Seems sort of odd with our upcoming repatriation that my box of razor blades is lasting longer than I did.
