High-quality materials: Made from selected high-quality materials for continuous, efficient, and easy-to-use performance. The best shaving effect: For optimal shaving results, we recommend replacing the shaving head every 18 months. After 18 months of use, the electric shaver may have trimmed over 6 million hairs, which can gradually reduce cutting performance. Special processing technology: The replacement head features special processing technology that enhances the appearance and texture of your shaver. Restore performance: Replacing the head helps restore your shaver's performance for a better shave. Regular replacement ensures the shaver remains in peak condition for years. Color: As shown.
