Snap closures are fasteners that consist of two parts: a male stud and a female socket. When pressed together, they create a secure closure that can be easily opened and closed. Snap closures are commonly used in clothing, bags, and various accessories due to their convenience and reliability. These closures come in various sizes and materials, including plastic and metal, making them versatile for different applications. They are often found in items like jackets, hats, and diaper covers, providing a simple solution for keeping items securely fastened while allowing for quick access when needed.
