The Clip Cose buckle, 32mm in diameter and red in color, is a quick-release plastic buckle composed of two pieces that snap together, used to close belts, backpack straps, collars, and other accessories where an easy, one-handed closure is desired. The red color makes the piece stand out, making it a popular choice for backpacks and accessories with a more vibrant style. It is a very common accessory in leather goods and functional sewing projects.
