Vintage Package of 5 Silk United Nations (UN) Flags

How great are these vintage little embellishments? This set of little flag picks is made of silk!

The tiny flags of France, the UN, the UK, Canada and the USA are together in the original packaging from Japan, probably from the 1960s, but we're really not sure of the date. These are new old stock, never used.

We're also not quite sure why these are the only countries represented! Each flag measures 2 inches wide by 1-1/4 inch high. The flagpoles are 3-1/4 inches from top to bottom.
