Royal Mail are changing the definitive stamps to be all self-adhesive, starting with the 5 low values - 1p, 2p, 5p, 10p, 20p.

Note that this is not regarded by Royal Mail as a new issue so there are no official first day covers. This is the set of 5 on first day cover with Birmingham postmark. Note because the minimum postage on covers to obtain a special handstamp must be the 1st class rate, additional 1p & 2p stamps have been added.

Also available mint stamps, cylinder blocks, and date blocks.
