Key Features:

Five Anti-Friction Blades: Gillette Fusion blades are known for their five-blade shaving surface. The blades are spaced closely together to help distribute pressure and reduce friction, aiming for a close and comfortable shave with less irritation.

Precision Trimmer: A key feature of the Fusion line is the single-blade trimmer on the back of the cartridge. This is specifically designed for styling and getting into hard-to-reach areas, such as under the nose, around sideburns, and for shaping facial hair.

Lubrication Strip: The cartridges come with a lubrication strip that helps the razor glide smoothly over the skin. This strip often fades to white over time, serving as an indicator that it's time to change the blade for an optimal shave.

Compatibility: Fusion cartridges are designed to be compatible with all Gillette Fusion, ProGlide, and ProShield razor handles, giving users flexibility with their razor system.

"Power" Version: Some Fusion blades are labeled as "Fusion Power" and are designed to work with battery-powered Gillette Fusion handles. These handles often have a micro-vibrations feature that some users find helps to reduce friction and improve the shaving experience.
