A belt box set is a collection of belts that are packaged together in a box. The belts in a belt box set may be similar in style, color, or material, or they may be a mix of different types of belts. Some belt box sets may also include other accessories, such as buckles or belt loops. This type of set is often given as a gift to someone who enjoys wearing belts or as a way to accessorize different outfits.
