Bristle Types: Gillette offers shaving brushes with different types of bristles. These may include natural bristles, such as boar hair or badger hair, or synthetic bristles. Each type of bristle offers a unique texture and performance during the lathering process. Handle Material: The handle of the shaving brush is typically designed to be ergonomic and comfortable to hold. Handles can be made from various materials, including plastic, wood, or metal, and may come in different shapes and sizes to suit individual preferences. Softness and Density: Shaving brushes vary in softness and density of the bristles. Softer brushes are often preferred by those with sensitive skin, while denser brushes can hold more lather and provide a luxurious feel during application.
