Three-Blade System: Like the standard Blue3, it uses three blades to provide a smooth and close shave.

Flexible Head: The "Flexi" designation is its main selling point. The flexible head pivots to adjust to the curves of your face and jawline, which helps the blades maintain optimal contact with the skin and reduces the need for repeated passes.

Enhanced Lubrastrip: It features an enhanced lubrication strip, often with ComfortGel technology and aloe, that helps the razor glide smoothly and comfortably over the skin, minimizing friction and irritation.

Ergonomic Handle: The razor is designed with a soft, Ultragrip handle for secure control and maneuverability, even when wet.

Easy Rinse Design: The open blade architecture is designed to allow for easy rinsing, which helps prevent clogging and keeps the blades cleaner.
