BOHIN curved safety pins will allow you to assemble your fabrics. They are especially used for patchwork and quilting. The curve makes it easy to go through several layers of fabric. 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.
