The item you're referring to is the Gillette Mach3 Razor Handle with 2 Blades (or Cartridges), which is one of Gillette's most popular shaving systems designed for a close and comfortable shave.

Here are the key features of the Mach3 system:

1. Razor Blades (Cartridges)

Triple-Blade System: Each cartridge contains three progressively aligned blades. This design is intended to cut hair gradually closer with a single stroke.

Stronger-Than-Steel Blades: The blades are engineered to be stronger than steel and stay sharper longer than some other Gillette blades (like Sensor3 disposables), with each refill typically engineered to last for up to 15 comfortable shaves.

Lubrication Strip (Lubrastrip): A lubrication strip is positioned at the top of the cartridge. It releases lubricants upon contact with water for a smooth glide and helps to protect your skin from redness. It fades to white when the shave is no longer optimal, indicating it's time to change the cartridge.
