Anyone know a good brand of bubble mailers that are durable and reliable for sending video games? If so then what other packaging do you use and do you send it as a large letter? I have tried a Padded Bag PB2 that you buy from the post office but it is too thick to be sent through a letter box with a game inside. (2cm)

These ones look pretty decent:
