Inventory
Everything the binder cannot hold: bulk lots, sealed product, fan gear, and the graded slabs we have no card record for. A graded card we already have a record for belongs on the card itself, in My Cards.
Bulk
Piles you count once: commons, energy, the Trainers box. One row is one lot.
Slabs
Graded cards we cannot match to a card record. If we know the card, the grade belongs on the card itself, in My Cards.
Sealed
Boxes, ETBs, tins and blisters, sealed or not.
Fan gear
Plush, figures, pins, apparel, games and everything else that is not a card.
