Gillette Mach3 Sensitive Disposable Razor
Gillette Mach3 Sensitive Men’s Disposable Razors feature 3 high definition blades for glide and comfort and an indicator lubrastrip, which fades to white to let you know when shave is no longer optimal. Great for sensitive skin, this razor has an enhanced lubrastrip with more lubricants released (vs. Mach3 regular disposables). A pivoting head provides incredible closeness. Complete with an ergonomic handle for great control and maneuverability.
