1 1/4" Gold Plate Mag7.5 Magnetic Clasp Converter. This has a lobster claw clasp and split rings. This is gold plate from start to finish. Magnet is 7.5mm round and 5/8" long. This is larger than the mag7 that we carry and also stronger too. Not as strong as the mag8 though. The silver plate magnet is a little more squared than the silver tone one. As with all magnetic clasps, SLIDE them apart, never PULL them apart. This is a good strong magnet and will work well for med to heavy weight jewelry
