It's normal to shave too closely at first. The more you use it, the sharper it becomes! It is recommended to replace the blade every 12 months. 【After-Sales Package】The package includes one blade and a small cleaning brush - If you have any questions within 14 days of receiving the product, please contact us in a timely manner. We will provide the best service! 【Please Note】This product is a compatible product and not a genuine Braun product. Please do not install it roughly, as it may damage the blade. We recommend purchasing the genuine product for customers who desire higher-quality shaving.
