BCW
A plain shoebox-style box. Cards stand upright, like books, with a divider if the row is short.
A heavy horizontal stack bows the cards at the bottom. Vertical, supported, in penny sleeves, in a dry cupboard. 400, 800 and larger counts exist — do not fill past the point they have to be jammed in.

Ultimate Guard
A hard deck box. 100+ fits a double-sleeved commander-sized stack; 60 is a tight Pokémon or Yu-Gi-Oh! deck.
Dice live in a separate compartment or a different box. Loose dice in with cards scratch sleeves and, eventually, corners.

Slots cut for PSA, CGC and similar slabs so they stand upright.
A slab is already the protection. Do not crack it to reseat the card. Keep slabs out of a sunny window — the label and the card can still fade.
