These brass pins are exceptionally suitable for pinning work on blouses, shirts, and curtains made of fine fabric. The pins have a burr-free, small metal head that serves as a grip-friendly pressure surface. They are fully made of rust-free brass. Their fine tip allows them to easily penetrate fabric without affecting the fibres. Prym sells these pins for domestic needs in small, plastic storage canisters and in large packages of 500 units for professional dressmakers.
