8 Cards of 1930s Flexible Fabric Covered Hair Curlers - All Slightly Foxed

8 1930s display card of 4 hair curlers.
All of them a  bit foxed, some more than others - see photos.
They are made from a very flexible metal covered in a soft woven light
or dark brown fabric. 6 dark brown , 2 light brown.
They are 6" long, so 3" when bent in half.
Seems as if they would be much kinder to hair than the frightening metal ones
that come later..
Perfect for creating vintage hair styles - using vintage tools !
The instructions, with diagrams, on the card says
"Place hair in centre and roll towards the head and finally bend both ends of curler over to secure"
