Cardboard, plastic or metal: in which do you store which items?

Cardboard, plastic, and rigid boxes each excel at different things. This is how you choose the right storage material for each location and type of item — and prevent flimsy boxes and condensation.
When you put something away, you rarely consciously choose a material. You grab the box that's there. Only months later do you notice the difference: a cardboard box in a damp basement has gone soggy, a plastic container in the attic has had condensation inside, and the small parts box is nowhere to be found because it ended up at the bottom of a large box. All three are material choices, not tidying mistakes.
Cardboard, plastic, metal, and rigid box materials all excel at different things. If you know what, you only need to think once about what goes where.
Cardboard: light, stackable, and breathable — but not for damp conditions
Cardboard is the cheapest storage material and the best for the vast majority of items. It breathes, so textiles and paper won't get a musty smell. It's light, stacks neatly, and you can write directly on it. An Action Moving Box 480x430x330 mm - 50 liter costs €3.50 and is large enough for bedding, clothing, or seasonal items. For smaller quantities, a Cardboard Shipping Box 15x15x15 cm - White for €1.99 is useful, precisely because you can place several of them side by side instead of stuffing everything into one large box.
Where cardboard fails: prolonged moisture, direct contact with a concrete floor, and weight pressing on the same spot for months. Two practical rules help a lot with this. Never place boxes directly on a basement or garage floor; use a shelf or slat. And keep the heaviest boxes at the bottom with a maximum of two layers on top, so the bottom box doesn't slowly collapse.
Plastic: when moisture is the real risk
Plastic containers and boxes have one clear advantage: they keep water out. For a shed, garage, or basement that occasionally gets damp, this is decisive. They also have one clear disadvantage that people often overlook: they don't breathe. If you store something that's still a bit damp — a tent, textiles, shoes — that moisture will remain, and you'll get mold. Everything that goes into plastic must be bone dry.
There's a category of items where it's not about moisture or dust, but about shape. Jewelry, small jewelry components, a watch, cufflinks: these get damaged by rubbing against each other. A box with a rigid base solves this and also saves searching.
Write the contents, not the room. "Attic 3" will mean nothing a year from now. "Winter coats + scarves" will.
Add the date. If something has been unopened for two winters, that's the best sign it can go.

Storing fragile items is different from shipping fragile items
For storage, you usually don't need to cushion against a fall, but you do against the shifting and bumping that occurs when you move the box. A layer of Bubble Wrap Roll 500 mm x 500 m Transparent for €12.95 between items is enough for this; whole layers around them waste space. For small portions you want to keep separate — screws, parts, remnants — Mini Pizza Boxes - 85x85x20mm - 100 Pieces for €10.00 are a cheap way to have a hundred small, stackable containers. And to open boxes without cutting into the contents: Utility Knives 3 Pieces for €4.95.
Start with the place, not the items
The practical order is: first, look at where something will be stored. If that place is dry and at a good temperature, cardboard is almost always good enough and the cheapest. If the place is damp, cold, or outside, plastic wins. If it's small and fragile, a rigid box wins. Only after you've answered that question does the size of the box come into play.
