Unused box of old Mode de Paris metal buttons used for workwear

These buttons can be found on all sorts of old pieces of workwear - they were mass manufactured from the end of the 19th century, and I am guessing this packet is anywhere from 1920-1950. Inside the buttons are perfect and shiny, and if this is a complete box there should be 144 buttons in total here. They are 1.5cm in diameter.
