The magnet on the keychain is comfortable to touch and very durable. It is the perfect size and strength to identify imitation silver or gold jewelry. Product Specifications Type: Neodymium Magnet Key Chain Material: Neodymium Dimensions: 0.47 x 1.69 inches (1.2 x 4.3 cm) Package Includes: Set of 4 Key Chain Magnets in a superbly packaged package Note: Storing a magnetic object such as a credit card with a magnet may cause damage to your cell phone or electronic devices Directions: Please test unknown jewelry first. If there is steel or iron, the magnet will adhere to it. These metals are included in jewelry electroplated with gold or silver, but are not included in high quality jewelry (the clasps are an exception and some metal springs may have an iron spring). However, please be aware that not all fake jewelry contain these metals as the base may be used with other non-magnetic metals. If you have passed the magnet test (those that do not react with magnets) you can see more details.
