Where can you buy bulk brass pendants online?

Tweet

I have been seeing these amazing brass octopus pendants (pictured) all over Etsy and from a variety of sellers. Clearly these people aren't making them and are buying them in bulk and I am would love to find out where I could buy my own bulk order. Do you have any ideas whatsoever of where these would be available? I tried Michael's, but had not luck. An online shop would be prefered.
