Europe up to 100 gram letter stamp. These stamps are valid in both EU and Non-EU countries. They are currently worth £1.85 each and they can also be used on inland UK mail. We have customers who combine them together for special delivery packages etc.
Most of these stamps come with lick and stick gum with perhaps only around 10% of what we buy having self-adhesive gum.
Note: These stamps are fully valid for postal use up to 31st January 2023 whereby they will no longer be valid so you will either need to use them or swap them for new stamps via the Royal Mail's 'SWAP OUT' scheme before the deadline.
