Points if you can identify the objects above. Years before the invention of blow dryers and circular hair brushes, rollers were the only way to achieve curly hair. My hair was stick straight in a time when poofy hair was in style. The solution was to roll up damp hair on these objects and sleep on them. They were wire spheres filled with sharp nylon spikes to catch the hair. They were held in place by the little white rods.
That looks like it would hurt. Yup! Got that right. Besides the pain of the nylon spikes, the white rods had a tendency to move in the night and end up poking me in the ear.
