Anyone know what kind of beads these are?

I find trade beads interesting but I never seem to see anything remotely like them when I do look, which is not that often.

I realize these seem to have some degree of being made by hand.

It looks like the wider pieces are some type of shell.

 

They look like they might be polymer clay.

 

It's brand new, whatever it is. Some sort of molded material .

 

You do know that these aren't anything like trade beads?

 

I was confusing it with beads/jewelry made by hand.
