I have no clue what these are.  

The round things measure approx 2 5/8" diameter by 3/4" wide.  

The larger geometric thing is approx 3 5/8" across and approx 1/2" wide.  

The red stick didn't come with them, it was just a cool way to show the geometric things each have 2 rubber grommet holes in the sides.  

The hooks on the round things seem like they fit into the geometric things.  

So here's the deal.  If you know what these are and need them, great.  

If not, you can always punk your friends with a gag gift.
