Key features of the Gillette Fusion5 blades include:

5 Anti-Friction Blades: The cartridges have five blades that are spaced closely together to help reduce pressure on the skin, which can lead to less irritation and a smoother shave.

Precision Trimmer: A single blade on the back of the cartridge is designed for styling and for reaching tricky areas, such as under the nose and around sideburns.

Lubrastrip: The lubrication strip at the top of the blades provides a smooth glide over the skin. It fades to white over time, serving as an indicator that it's time to change the blade for an optimal shave.

Microfins: Soft microfins precede the blades to gently stretch and smooth the skin, preparing the hairs for a close cut.
