Expansion 2

Vintage rhinestone cuffs. Beautifully set and highly reflective. Much of the stones are clear but if you look closely, at the one resting on top, you'll see hints of smokey grey. Both unfold. Imagine an accordion or, for the kids born in the 70s and 80s, one of those expandable colanders everybody had in their kitchen. 

The metal is steel of some sort or tin, I think, which I'm guessing we all have to thank for their near perfect condition.
