The Gillette Razor is a popular brand of safety razor that was first introduced in 1901 by King C. Gillette. The company has since become a leader in the shaving industry, producing a variety of razors for both men and women. Two of the most popular models are the TracII and the Atra. The TracII is a two-blade razor that features a pivoting head for a closer shave. The Atra is a four-blade razor that provides a smooth and comfortable shave. Both models are designed to provide a close and comfortable shave with minimal irritation.
