Quote from the gov website:

To mark the unique occasion of Her Majesty The Queen’s Diamond Jubilee, Fortnum and Mason is presenting all Armed Forces personnel on active service with the ‘United Services Tin’, containing tea and biscuits.

The gift is intended to ensure that each recipient in the Army, Navy and RAF will be able to join the rest of the nation in celebrating Her Majesty’s Diamond Jubilee Weekend on 2-5 June 2012.

15,000 tins are already en route to servicemen and women across the world, so that they will arrive in good time for the Jubilee weekend.

Fortnum and Mason has worked closely with the MOD to create the smart ‘United Services Tin’. The tin, in white, and decorated with Fortnum’s signature eau de nil and the insignia of each Service, contains Fortnum’s Queen Anne tea and clotted cream digestive biscuits.

The Tin is empty.

Card included.
