Job Lot of 5 Vintage Diamante Hair Bands (tarnished)

Job Lot of 5 Vintage Hair Bands, 4 different designs.
They are made of plastic with metal and diamante decorations on top.
The metal is tarnished and 1 of the stones is missing.
They are small but could probably be loosened and opened up ..by someone who knows how to work with plastic.
Or, of course, turned into something even more exciting...
