Vintage?? Jac-O-Net Hide-Away Truly Invisible Hair Net-pkg of 3 in original pkgNo. 358 - Black - NylonMade in USAHide-Away Elastic in Back3 Hair Nets - still in package - I did not stretch them out to be sure they were O.K. but should be since they are still new, however, you purchase "As Is".I am not sure of the age. This package sold for $.49 when new, on sale for $.37 so that should be some indication of the age of this item.Nice "Hair Accessories" Collectors item.
