The FIDES Round Handle, crafted from high-quality aluminum alloy, is designed primarily for indoor use, such as on wardrobes, kitchen cabinets, or drawers. While its robust construction ensures durability and long-lasting performance, it is not specifically treated for outdoor conditions, which can include exposure to moisture, extreme temperatures, and UV rays. For optimal performance and longevity, we recommend using it in indoor settings where it can maintain its elegant and modern appearance.
