Temperature and Humidity: The Hidden Enemies of Collectors

Temperature and humidity are often underestimated by collectors, yet they play a crucial role in the long-term preservation of statues and figures.

Unlike sunlight, their effects are not immediately visible, but they act slowly and can cause significant and sometimes irreversible damage.

Temperature effects on materials

Resin, PVC, and ABS react differently to temperature changes.

Extreme cold can make resin more rigid and brittle, increasing the risk of breakage during handling, especially on thin or protruding parts.

Excessive heat, on the other hand, may soften plastics, weaken adhesives, or cause slight deformation in delicate areas.

Repeated temperature fluctuations are even more harmful, as they create internal stress within the material over time.

The impact of humidity

Humidity is a silent but serious threat to any collection.

High humidity levels can lead to:

• deterioration of original boxes and packaging
• mold growth on cardboard materials
• weakening of protective foam inserts
• long-term paint degradation in extreme cases

Conversely, overly dry air can also make some materials more brittle and sensitive to impact.

Environments to avoid

Certain locations are particularly unsuitable for storing or displaying collectibles:

• damp basements
• attics with strong temperature fluctuations
• poorly insulated rooms
• areas near direct heat sources such as radiators

These environments often combine multiple risk factors at once.

Ideal preservation conditions

To properly preserve a collection, it is recommended to maintain:

• a stable, moderate temperature
• controlled humidity levels
• a ventilated room without direct airflow on the pieces

A hygrometer is a simple tool to monitor these conditions.

Stability matters more than perfection

Stability is more important than achieving a perfect theoretical value.

A collection kept in a slightly imperfect but stable environment will always be better preserved than one exposed to constant fluctuations.

Long-term preservation

Temperature and humidity are silent enemies. Unlike accidental damage, their effects accumulate slowly over time.

A controlled environment helps preserve not only the appearance of statues and figures, but also their structural integrity and packaging condition.
