I will be shipping this pack with "eBay Standard Envelope". The rules of this envelope state that it cannot be too thick, so please expect your order to be packaged as follows: the pack will be slid inside of a card saver which will be taped to the packing slip, and put in the envelope to ship. If you would like it shipped in a box or padded mailer, please choose the USPS Ground Advantage shipping option when you check out.
