Flatten or keep assembled?
Flatten, for almost everyone. An assembled box takes several times the volume and gains nothing, and a carefully flattened box in good condition can be reassembled when you need it. Open the glued seams gently rather than tearing them, and keep the inner tray flat alongside it.
The exception is a sealed Funko you are holding as an investment. Opening it is the single largest reduction in value you can perform in one action, so those stay assembled, sealed and in a protector.
Where to store them
- Off the floor. Monsoon water ingress and floor-level humidity are the two things that ruin stored cardboard.
- In a sealed plastic box or bag rather than open on a shelf, with a few silica gel sachets. Refresh or replace the sachets each year.
- Flat, not on edge. Boxes stored upright bow, and a bowed box will not sit square when reassembled.
- Away from sunlight, which yellows a Funko window in storage exactly as it does on display.
- Not inside the display cabinet with the figures — see below.
Why boxes should not touch the figure
Two reasons. Cardboard and the printing on it are mildly acidic, and prolonged direct contact with painted PVC can mark it. And moulded plastic trays press against the figure at a few specific points; under sustained heat those points can imprint or dull the paint.
This is why a figure that has sat in its tray in a hot cupboard for three years sometimes comes out with a faint mark across a thigh or a shoulder. If you are storing a figure long term rather than displaying it, wrap it in acid-free tissue and store it beside its tray rather than inside it.
What box condition is actually worth
| Format | How much the box matters |
|---|---|
| Funko Pop | A great deal. Corner sharpness, window clarity and creasing are graded, and stickers only exist on the box. |
| Retail scale figure | Moderately. Buyers expect the box, and a damaged one reduces the price, but grading is far less exacting than for Pops. |
| Prize figure | Little. The packaging is light and nobody grades it; the figure is what is being bought. |
| Nendoroid / figma | Little for value, but keep the tray — it holds the small parts, and those are not sold separately. |
