Super Strong Neodymium Pocket Chain Split Ring Keyrings Jewelry Test Magnet Holder
This is a powerful neodymium-iron-boron magnet in a brass or nickel casing for industrial and hobby use. It comes with an extra heavy duty split ring for attaching a belt loop, hook, rope, wire, fishing line, etc.
The casing protects the magnet from chipping and breaking, and makes removing iron and steel shavings much easier. A tight fitting vinyl cap is also included to protect the magnet when it is not in use. This also helps keep the magnet from attracting iron dust and steel chips, as well as offering a little buffer to the magnet's strength when it is not being used.
