Box of 72 Black PRINCESS GRIP Hair Pins

Box of 72 Black PRINCESS GRIP Hair Pins.
Probably from the 1950s.
Some of the black enamel on the pins has gone a bit bobbly.
The pins are 4.5cm long and the cards are 7.5cm long.
12 pins on a card
There would be plenty you could use, or even better, imagine Art Works 
made from repeats of HIGH-CLASS QUALITY PRINCESS GRIP cards..
Also, for those of you that need lots of little bits of thin metal to poke into things, support things, build things - here's 864 of them.
Come in their own, compostable, cardboard box 
(I must have the most vintage compost bin in the country...)
