Very cool find!
17 Vintage LEATHER Hair Curlers SPLIT CENTER SNAP CLOSURE Rollers Curly Q RARE
You roll your hair thru the split in the leather and then you snap the button closed and voila.
See closeups of the curlers as there is wear and discoloration but they all bend and snap well.
They have the old storage smell but I have febreezed old items in the past and it was very helpful.
I think they are neat.
The last two photos are screen shots I found online that you can print out for instructions.
I can combine shipping on multiple listings.
