"I've bought these razor blades (which I cannot find in drug stores, etc anymore) several times from this seller.... I'm slowly acquiring lifetime supply. New razors and blades are unbelievably expensive by comparison. Very reliable seller. Great product, Fast shipping. Recommended seller! Thnx, Super Safety Razors!"
