69p stamps!

Sorry to be so mundane, but the beak of the goose is 1cm oversize (things-you-think-of-too-late!) so can you make sure you put correct postage on your goose otherwise I’m going to be paying a lot of money to get them back.. one or two arriving a little ‘underdone’.. Thank you!? It will be 69p for a ‘large letter’ stamp within the UK. You should be able to stick a stamp on the addressed side and stick it in the postbox, no need for an envelope!
