This set includes four magnet keychains designed primarily for metal verification purposes. The strong magnets provide reliable detection of ferrous metals and differentiation from non-ferrous metals such as brass, silver, and gold. Each unit is constructed with a durable casing that protects the magnet while maintaining its effectiveness. The keychain design ensures the magnets remain portable and accessible whenever testing is required. These keychains are suitable for use by hobbyists, jewellery workers, scrap metal sorters, and professionals who regularly encounter various metal types. The set of four offers multiple units for different locations or users. The compact size allows for easy storage in pockets, toolboxes, or workstations. The magnets provide consistent performance under normal use conditions.
