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

This is a set of cylinder blocks of 4, as shown with printing dates 04/1/11 and 05/01/11 (1p).

Random grid positions are shown, please state a preference if you have one and we will try to supply it.

Because of their low value, these are sold as a unit of the 5 stamps. Also available mint sets, date blocks, and FDCs.
