FREEPOST address

[roisin]

I have a FREEPOST envelope but it's not big enough.

Can I write the FREEPOST address on a bigger envelope to send, or do I need to put stamps on?

Sorry if this is a really dim question
I need to be 100% certain it will get there.

Does anyone know whether it will go first or second class?

dont know about the first class 2nd class thing but the freepost will still work :)

what about sticking the FREEPOST envelope onto the bigger envelope
