I would use three large letter stamps which are available from the Royal Mail shop - if you need any PM me and I would be happy to assist.
Howver, I would recommend using a £1 stamp and a 5p stamp which should also be available online.

osiris, thanks a lot for listing the prices for me

The terms "first class", "second class", "large letter" and "letter" stamps aren't applicable for Overseas mail They are only for internal mail, as in a First Class stamp will get your letter to its destination in one day, using either a regular stamp or a "large letter" stamp, depending on size of the letter. A Second Class will get there in 2-3 days.

For international mail, the only thing you need to worry about is the price, in this case £1.05. You can use any combination of stamps (class or unclassed) as long as it covers this price. Simply stick your stamps on, and write "Par Avion - By Airmail" on the top left corner.

You can get unclassed stamps in many denominations e.g. £1, 50p, 20p, 5p, 2p, 1p. As classed stamps are easier to come by, I'll list the prices of them for you

1st Class Regular - 39p
1st Class Large - 61p
2nd Class Regular - 30p
2nd Class Large - 47p

Thank you so much for your help! {thumb2}

Hi 19Gadell92,

Large letter stamps are now worth £0.62, so if you have found that you need £1.05 for your SASE, you will need 2 large letter stamps for your envelope.

Best of luck with your request! {thumb2}

Here's Royal Mail's details on sending to Sweden.

I can give you advice which isnt probably that accurate or necessery right.

If a large 1st class stamp is 48p(cant seem to find a price list. Its 48p or 52p im sure) and it will cost you £1.05 then i think you need 3 large 1st class stamps {thumb2}

Dont send your letter off until you check with someone though. Like i said im just giving it a bit of thought {thumb2}

Hi
I'm going to send to a venue in the U.K, and my SASE will probably weigh no more than 50grams. It says on Royal Mail that it will cost £1.05 to send it from the U.K to Sweden. Since my envelope is pretty big (A4) I'm thinking of using something called Large Letter stamp, but I can't find anything on how many Large Letter stamps I need to put on my SASE in order for it to 'come back' to me. This is what it says on Royal Mail: "First Class stamps for Large Letters: these are items between 240 and 353 mm in length, 165 and 250 mm wide, and 5 to 25 mm thick, and weighing up to 100 grams. This includes most A4 documents, CDs and magazines." It says nothing about sending overseas. How many Large Letter stamps do I have to put on my SASE for it to come back to Sweden?

Any help is highly appreciated!
