The Hi-Tech Big Blue Faux Hog Hair Brush features blue Nog Hair synthetic nylon bristles that closely mimic the feel and cleaning performance of natural hog hair while offering greater durability. Its multi-level construction provides extended surface coverage and excellent soap retention, making it ideal for applying soap to most areas of your vehicle while helping prevent the brush block from contacting the surface. With 3" bristles, overall dimensions of 14" x 3.5", and an 8" block, this brush fits standard threaded handles for convenient use.
