Room before accessories
A premium sleeve cannot compensate for a leaking pipe, recurring condensation or an inaccessible stack. Review the room first, then the outer box or binder, then the card enclosure.
- Keep storage above floor level and away from water paths.
- Prefer a lived-in room with fewer seasonal swings.
- Use closed storage where light reaches the shelf.
- Leave enough access to inspect without unstacking everything.
- Do not force a full binder, box or closure.
What this check cannot establish
It does not measure temperature, relative humidity, pollutants or material compatibility, and a clear result is not a guarantee. Recheck after leaks, building work, unusual weather or a long gap between inspections.
