VAXTCOKG SH91/52 Replacement Blades/Heads Compatible with Philips Norelco 9000 Series Shavers, Replacement Head with Precision Dual Layer Blades.(2-SH91)

Optimization of blade density - Three-dimensional blade arrangement improves shaving speed and double-layer blade design reduces repeated friction and skin irritation. Quick Release Replacement System The snap-on design can be disassembled with a wrench, without tools, and the replacement can be completed in 3 seconds, which reduces the threshold for users. Lubrication Strip Integration - The cutting head has a built-in silicone-based lubrication strip to reduce friction between the blade and the skin and improve the smoothness of shaving. ERGONOMIC DESIGN - The arc of the cutting head adapts to the contours of the face (such as the curves of the chin and neck) and supports multi-angle flotation, which improves the flexibility of operation. Compatibility & Adaptation Accurately match the model to ensure that the cutter head is synchronized with the body buckle and motor speed to avoid performance loss.
