3-Blade System: The Mach3 is defined by its three progressively aligned blades. This design is intended to cut hair closer to the skin with each pass, aiming for a smooth and comfortable shave with less irritation.

Lubrication Strip: These blades are equipped with a lubrication strip, which glides over the skin to help protect it from redness and irritation. The strip often fades to white over time, signaling that it's time to replace the cartridge.

Microfin Skin Guard: The blade cartridges typically include a series of soft microfins that stretch the skin and prepare the hair to be cut, helping to create a smooth surface for a closer shave.

Cross-Compatibility: A significant advantage of the Mach3 system is that all Mach3 blade refills (including Mach3 Turbo, Mach3 Sensitive, and other variants) are designed to fit all Mach3 handles. This means you can use these "Simple" 2-pack cartridges with any Mach3 handle you may already own.

Durability: Gillette markets its Mach3 blades as being "stronger-than-steel" and engineered to provide up to 15 comfortable shaves per cartridge.
