1991 Mattel Barbie Bike Helmet 1-7 Yr New in Box *Collectible only,not for use*

VTG 1991 Mattel Barbie Bike Helmet 1-7 Years Brand New in Box Made in Mexico ***I would consider this item a Barbie collectible from 1991 and would not recommend using this bike helmet as actual protective equipment when riding a bike ***The item is extremely old and I am not sure how long the plastic and foam would stay structurally sound or if satefy regulations have changed in 30+ years.***
