The Xtreme 3 Razor Blades have been designed for use with the Wilkinson Sword Xtreme 3 Razor. Using 3 completely flexible blades which adapt to the contours of your face, you'll get a really comfy, precise shave. In addition, the microglide bar helps raise the hair before shaving and lubrication strips (infused with Aloe Vera and Jojoba) give an ultra smooth shave. It's great for the pocket too meaning you don't have to compromise on razor quality or performance.
