Used vintage lot of 10 Key Car 'Fobs'.

These came off a display rack for a product called 'The Clincher' which is the center plastic piece the key goes in.  I don't see any of listings really calling it the clincher.

I think these are from around the 1970s.  Features the following car brands

Datsun, Toyota, Dodge, Vega, Pinto, Chevelle, AMC, Plymouth. 

The plastic from coat on the orange plymouth one has melta and is kind of stuck.  That is the only one i cannot get the metal key to pull back in.  These are not intended for use - should just be purchased for the sake of collecting.

Last pic of the rack is for name reference only - this listing is just for the 10 key fobs shown in the pictures
