Anyone have experience with sending small items, i.e. small, flat, light, but stiff with Express Post Envelope?
I mostly send my items as a regular letter with $1.10 stamp on a 11x11x0.5cm pouch.
So far I've sent 2 of these items with Australia Post's Small Prepaid Express Post Envelope $7.50 - ish, and they went through just fine.
Though the Australia Post lady in the counter told me that I'm not supposed to send anything with the Express Post Envelope other than documents.
I'm thinking to just send it anyway, but maybe use Medium size express envelope, to do this. Will it be okay? Other alternative is to send it as a small express parcel at $11.50, but that is really too pricey and I don't think it is sustainable. Anyone have any insight on this?
Edit: Item is handmade acrylic keychain
