Vintage 1940s Thin Black 4.5cm Crimped Hair Pins - 20 in a Roll

DELICATE SOFT BLACK  5CM CRIMPED HAIR PINS.

20 of then come in their original paper roll.

They are 4.5cm long, black and thin but strong - more suitable for fine hair....

These could be earlier than 1940s - I found them in an old warehouse clearance.
