Worldwide Postcard up to 10 grams Die- Cut stamp. From 1st January 2021 these can be used on worldwide letters up to 20 grams or European letters up to 100 grams.
These stamps are exactly the same as the standard postcard stamps except for the fact they are cut flush to their cardboard backing. This does make the backing difficult to remove hence why we sell them a little bit cheaper than the stamps which come in booklets of four..
If you can't be bothered removing the backing you can easily stick the stamps on using a glue stick. This approach is perfectly fine as the stamps have never been through the postal network. The stamps were originally produced to put in Royal Mail presentation packs.
