DL safety pins refer to a specific type of safety pin known for its elongated shape and design. These safety pins are longer and narrower compared to traditional safety pins, making them suitable for specific applications such as tagging or securing fabrics in a way that requires a sleeker profile. DL safety pins are commonly used in the garment industry, particularly for attaching tags, labels, or securing fabric layers during sewing or crafting projects. The elongated shape allows them to penetrate multiple layers of fabric easily while providing a secure hold.
