This is a brand new, factory sealed, official Pokemon TCG Lost Origin booster pack. This listing is for 1 single pack. 1 pack contains 10 playing cards and 1 code card. USPS seems to have issues if more than 1 pack is included per envelope. It fits every one of their shipping guidelines/standards, but in my experience it causes issues, so if you purchase more than 1 pack, each and every pack will be sent in it's own individual envelope.
