I just tried to contact mann optics regarding these brooches using the email address and form on their site, but it bounced. Do you have any contact for them?"

I’m not sure what country you live in but if it is not Australia and
you are trying to contact Mann to make an order you may be better
off to find an optical supplier in your own country. Also, as a
wholesaler they can probably only deal with businesses - just in
case this affects you.
Hope this helps.
