Seven flat plastic cars.  Marked HONG KONG on the sides.

The cars you see are the cars you will get. 

I do not know their original purpose.  I purchased them with old toys - so maybe toys or party favors.

Each car is approximately 2 1/4 inches long.  Likely 1960s or 70s Era. 

The plastic has some uneven colors - see photos.

Other than the uneven color - they look ok for age and material.   They have normal manufacture imperfections and light wear.

Retro cheapo toys or party favors.  Intended for adult collectors only - no telling what they are made of.

For my info - lot #5
