Base metal bracelet supplier?

A friend and I have been using bracelet blanks like this-

(only silver-tone) in our low-end lines. We’ve been getting them
from Eloxite, but they are often out of stock, and we have been less
than thrilled with their customer service. Does anyone else know of
another supplier for these?

Thanks, Karuna
