Button Floozies

Here are 3 buttons from a jar with hundreds of vintage buttons.  Check these out: They have the look of little nests of fresh pasta. They are made of resin and plastic. They really stood out in the jar of buttons that I found at a church yard sale. I am not sure of the age, type, or origin. Do you have any information on this type of button?

Hi everyone, I recently sorted out my buttons. I came across these and was wondering if anyone knows anything about them. The clear ones feel like glass, they are a heavy button. The ones on the paper are metal. You can see one of them has tarnished. The other one, shaped like a tear drop, is bone I think? Not sure about that. Just a wild guess.
