i just have a quick question for you all in regards to packaging when selling cards. now after a quick look i see that the general rule of thumb to send cards is for the card to be put in a sleeve and toploader which is to be taped, sandwiched in cardboard and send in a padded mailer. but i would like to know if the padded bag is a must? cause i have bought a few cards from other places (EBay and Facebook) and have seen that quite a few of them come in a C6 envelope along with the standard toploader and cardboard etc. only asking cause i am looking to sell of quite a few cards in the following weeks and the C6 envelopes are cheaper to get in bulk. TL,DR: Are C6 envelopes acceptable or are padded bags the law?
