Material: The shaver blade is made of high-quality material, enabling both wet and dry shaving, and is washable. Fine Protective Net: The rounded edges of the protective net are 360 degrees contoured to fit your face, and the precision slots easily catch whiskers and hairs. This allows for a safe and smooth shave without scratching. Sharp Blades: This upgraded replacement blade head improves shaving efficiency and saves time. The sharp blades help avoid pulling on whiskers and hairs. Easy to Install: Replace the shaving heads in a few minutes. After installation, apply a small drop of baby oil to each head and run the shaver for 10 seconds to ensure smooth operation. For best results, replace the shaving heads every 12 months.
