This unique pendant is held together by a magnetic clasp using our 25x5x2.5mm neodymium block magnet.
Note that this magnet has been discontinued but we can order it if you need some.
We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

We also provide complete Documentation including MSDS & ROHS; see below.
Titanium tweezers can be used to handle small block magnets & position them easily. The Mark I Magnaprobe is ultra sensitive & can be used to check stray magnetic fields. The Mark II Magnaprobe is a fast & convenient way to confirm magnet are positioned with their poles pointing correctly.
