My name is Claire, I'm French !
I'm sorry, but I don't find where to put my question... This is my first try =)
I want to send in england 2 photos (of Richard Armitage)
* I have a shell 22.5cm / 16.1cm
* I have a lot of 2nd Royal Mail stamps
(Above it is written 240mm long
165mm wide
100g weight)
* I didn't photos, but it will be about 50g max ! I'm afraid that will not be enough, so I put two stamps!

I want to send and other shell at Aidan Turner in Ireland (identical size), but I don't find stamps of Irland, so I buy international reply coupon

No information on the weight, so I asked to the post office, it told me that 1 coupon = 20g
Did I properly prepared mail ?
Is it that there is enough postage on the envelope for France?
Thank you very much =)
