I want to send my pal some stuff which I don't like to be folded.
Are bigger than the normal letter- envelopes allowed?

Cannot answer, me too I am asking myself if I can send like 8X11 size envelope? Sometimes I use 5X9 enveloppe, so I only fold once my sheets, but, when I write more that would be great to use bigger enveloppes as well!

I called them. The lady on the phone was really unfriendly 'they are not allowed to have postes ma'am'. "Yeah but I asked for the bigger envelope, is that allowed'. 'Yes ma'am, bye'.

So yeah. There's a name for them but I forgot, something starting with an 'M' I belive. But anyway, the envelopes that are as big as a papersheet from a writepad are allowed. Be careful though, you have to put a lot more stamps on them, because they envelopes are pretty heavy! (weigh much)

hmm I just sent my pp a 10x15 cm picture, I wonder if that will go through then. Hope I put enough stamps on it, 2 worldpost priority stamps, I mean that should be enough??

Yeah!
The pic is allowed (at least, that is if your pp is in AZDOC haha) and you need the second stamp only if you go over 20 grams.
Which is about 8 pages of writing paper.

good thing i put on the second stamp then I don't think 4 pieces of paper and 7 pics should exceed 50 grams...
