Item description according to supplier: BOHIN black safety pins will allow you to assemble your fabrics. They are especially used for patchwork and quilting. More generally speaking, they are used in many everyday situations. Nickel-plated steel makes them highly resistant to oxidation. Their curved shape makes it easier to pierce and fix several layers of fabric. As nickel-plated steel has a balanced elastic force, these pins will keep a high closing force despite frequent use.
