This never-used clutch is a vintage Walborg and was made in Macau.
The white synthetic backing and lining are probably acetate.
The top has a snap closure and opens to reveal a large compartment with an arc shaped opening and an inner open pocket.
There is a tiny bead missing on the top side and one on one of the vertical sides.
They're really not noticeable.
It's from a former British model.
5 3/4" high by 9" at its widest
