Mystery pack of Mother of Pearl Buckles in Original Brown Paper circa 1920s - 40s

Vintage haberdashery, lots of lovely cotton reels and a sewing project or two on the go.  What about having a pack of lovely old mother of pearl buckles?  Each one of these rectangular buckles is ready to go onto a ribbon belt or to decorate a hat band, or they would look lovely in a collection of sewing items.  There is a little suprise here -  I was told there are a dozen in each parcel but I didn't want to undo the original brown paper and string, it is too lovely.  I have felt them and I think there might only be 10 in total so I offer to you a pack of mother of pearl buckles and a chance on how many you get - maybe 10 buckles may be 12!  Each buckle will be in 'as new'  condition being wrapped up and they should all be nice and white and shiny like the example on top of the package.  Dimensions are approx 4.5 cms x 3cms.

By the way they date from between the 1920s and the 1940s so are vintage! Price quoted is for the package.
