Hello,
Unfortunately, we do not have those clasps available on our website :( I did do a Google search and saw that Hobby Lobby had them on their website. Here is the link to them:

I am not sure if that is exactly what you are looking for but that's what came up when I used the search engine?! Hope this helps!
