The full-size box sold through card shops rather than big-box stores. It has the most packs and the best odds, and most modern hobby boxes guarantee at least one autograph or memorabilia card. Pack and card counts vary by product line. Older listings sometimes call this a wax box.
Cases
The factory-sealed carton a product ships in, holding a set number of boxes. A full case is the whole carton; an inner case is a smaller sealed block from inside it. Case buyers get untouched pack sequencing and a lower price per box. Some rare cards are seeded about once per case, which is what collectors mean by a case hit.
