No Rust, No Warping: Metal extenders can rust your shirt if left on during washing. They also lose their shape quickly and can become deformed. On top of that, metal can be uncomfortable against the skin. Our elastic button extenders are a better choice - they don’t rust, don’t deform, they are soft and machine washable for long-lasting comfort and convenience.
