I have seen similar ones from..Cera? is it? but not this exact style. Reason i am asking is because i have a set of 7 now(one broke) and i am trying to track down a replacement. Easier to sell a set of 8 then 7. thank you!
You can start......
Here is a link that might be useful: here
Believe it or not i have searched many a page at replacements ....not fun.
