Choice of 5 Colours -1940s Kirby 7cm Enamel Hair Slides on Original Packaging

A display card of of unused 1940/50s KIRBY BEARD "Quality BOB PINS"
The slides are enameled metal, 7cm long and 5mm wide.
Here's a comment left by a good customer
"The original Kirby grips are fantastic. I can't believe how well they hold hair compared to the modern ones. Thanks so much. The stock is fabulous."
These were found in an old warehouse clearance and some of the cards consequently show some signs of age and long years in storage !
I have them in the colours shown.
