Large 1st Class (£1.01) made up of three stamp combinations, with mixed designs e.g. 65p + 18p + 18p etc. Using three stamps will give you additional savings. The majority of these stamps only come with lick and stick gum. This is the Royal Mail's new rate from 26th March 2018.
£1.01 is quite an awkward rate to make from existing stamps so we will probably have to sell them smaller quantities.
