I say use the harder photo mailer if you are really worried about bending, Its pretty much all I use because it only takes one mailman to ruin your autograph usually by accident because they don't know whats inside or possibly don't care so I would say use the rigid envelopes.

thanks so much for the great help

I've rarely had an issue from UK to USA and back again with 6x4's getting bent, using normal paper envelopes.
But if it's something really special to you then I would go for the cardboard envelope

i live in a country that is pretty safe and i was just wondering i live in europe and i would like to send a letter over america but it will be the A4 envelope that is made of paper like the standard ones. this really has to get to the person.

so should i go for the A4 paper envelope which is cheaper but might get bent or the sturdy A4 cardboard envelope which is more expensive? which one is more safe?

Thanks for all the help!!
