Fanmail.biz

Hi guys.

I sent a lot fanmails so far and I got many back. I send always an return envelope with, but sometimes I got an other (bigger) envelope with a cardboard inside back. Now my question. Where can I find this kind of envelopes with cardboards inside?

Thx!

I think you can find them at office supply stores. they basically just have a piece of cardboard for the back of the envelope. just type in 'cardboard backed envelopes' on google and you should find what you're looking for.
