This listing is for 11 little erasers, 5 each of yellow and blue 1970's cars.  They would have been used as small pieces to add to little gift bags given out at birthday parties.  There is additionally, 1 little tow truck (in case the little cars break down, LOL).  They are fun little kitschy pieces, great to display.  They will work on erasing pencil.  These are unused.
