The magnets finally arrived today so I was able to put together the test bracelet. The bracelet was made as an experiment for a red lantern collar using a magnetic fastener rather than a screw fastener. Advantage being these can be removed without a tool and there are no fasteners to lose.

The magnets are quite strong and it takes some leverage to pull the two pieces apart, no worries about it falling apart.

I keyed the ends so that it couldn't be twisted out but I may just go with straight ends for the next one.
