It typically consists of a clip that attaches to the back of an item, allowing for easy attachment and removal. This design is often found in items like hair accessories and clothing fasteners. Back-clips are favored for their convenience and ease of use. They provide a secure hold while allowing users to quickly adjust or remove the item as needed. This makes them popular in products like brooches and suspenders, where functionality and style are important.
