Gillette blades are very sharp, allowing for good results even without shaving cream. Regular Replacement: The razor head should be replaced once a month. This is because razor components wear down over time, reducing the razor's performance. Easy to Clean: Insert the Gillette knife holder into the blade groove and replace it in one second. Rinse with water after shaving, and the blades will not rust. Warning: The replacement blades are not Gilead products, nor are they Gilead licensed products.
