aluminum, and non-magnetic stainless steel materials, and solid brass and bronze from electroplated steel items\u003c\/li\u003e\u003cli\u003e【Jewelry \u0026 Coin Tester】- Use magnetic testing to quickly identify counterfeit or electroplated jewelry. Due to the fact that counterfeit jewelry usually contains steel or nickel, which has magnetism and is easy to adsorb, the authenticity of coins and jewelry can be preliminarily determined\u003c\/li\u003e\u003cli\u003e【Practical Magnetic Keychain】- Pocket Magnet key chain have small size, light weight, and are easy to carry. When going out, you can directly put the magnet key holders in your pocket or wallet, which is not only not easy to lose, but also very convenient for daily testing of iron, nickel, or cobalt at any time\u003c\/li\u003e\u003cli\u003e【Superior Quality Magnetic Key Chain】- Rare earth keychain test magnets use premium neodymium iron boron magnets and high-quality electroplating protective layer. Neodymium magnet key holders has strong wear resistance and corrosion resistance, long service life, and can be reused multiple times. Key chain for testing brass are suitable for jewelry dealers, metal recyclers, brokers, antique buyers, and collectors!\u003c\/li\u003e\u003cli\u003e【Widely Applications】- Gold testing keychain magnets can also be used for refrigerator magnets, whiteboard magnets, office magnets, process magnets, DIY magnets, miniature models, 3D printing projects, science, industry, educational needs, jewelry production, home decoration projects, fixation, salvage, and distinguish for stainless steel. Exquisite packaging is the best choice for giving to relatives or friends.\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eProduct Details\u003c\/h4\u003e\u003ctable
