1930s Made in Czecho-Slovakia Card of 12 Hair Clips that Need Some Crystals Replacing - 2 Designs

Two very 1930s designs, 6 of each on this card of 12 Hair Clips 
(possibly even the 1920s )
They all need some crystals replacing.
Made in Czecho-Slovakia printed on the bottom of the card.
Czechoslovakia was famous for its high quality rhinestone production
during the 1920s and 30s
Replacing the rhinestones would be a satisfying (and lucrative) job for the
nimble fingered and clear sighted amongst you.
I'm including one that has lost its back that you can mine for stones.
The stones are quite loose - I've put the sheet in a sealed plastic bag.
If you buy these - check the bottom of the plastic bag for any  that have
fallen out during transit.
