Vintage 1970 chattering teeth, wind up key plastic novelty toy retro dentures!

70s vintage plastic Talking Teeth in the original box dated 1970. These are roughly life-size, about 2 1/2" x 2 1/2". They're plastic (made in Hong Kong) with metal winding mechanism.

The box is worn, and these have only the built in key (the separate key originally included is missing). But they're bright and clean, and working fine!
