Global mix with several countries. 1950/2020 - Thousands of stamps, 3 kg on fragments from different countries, in small and large formats. - Yvert

Worldwide mix of thousands of stamps on a 3 kg fragment, small and large formats
See photos for details
Each kilogram of the mix is different, whether on fragments or those that are paper-free
Earlier I made mixes of 6 kilograms or more, but the shipping costs from Bpost turned out far too expensive, which is why I now offer 3 kg mixes.
If interested, you can come pick up the kilos at my home; I still have 150 kg in stock.
