Colourful Vintage Wimberdar Casein 10" 3.25mm wide Knitting Needles

Unused Wimberdar Knitting Needles.
Lots of attractive colours to compliment your knitting projects.
Made of casein, a plastic made of milk protein which predates modern plastics.
I've been told these are very warm and comfortable to knit with.
Probably from the 1950s.
They are gauge 10 which is 3.25mm wide and 10" long
Made in England.
I have several boxes as well.
36 pairs come in a box.
I'm selling them individually - choose a colour, or a whole box of 36.
