Vtg 1” Car Novelty Hook Earrings Rhinestone Headlights Marked MK

They have the MK mark on the front but I’m not sure if the are the real deal or knock offs?? Or just regular novelty earrings with those letters on them.

One is slightly more pink the than other (see pictures) but hardly noticeable to the naked eye. Other than that, they are in good wearable condition.
