description	Use when storing cards (raw or slabbed) long-term. Climate is the killer for cardstock over decades.

Climate Storage Best Practices

Cards need: 65-72°F, 35-50% RH, no UV, no pressure. Climate-controlled storage extends usable life decades.

Storage parameters

Optimal:

• Temperature 65-72°F (stable, no swings)
• Humidity 35-50% RH (avoid >55% or <30%)
• Light: no UV; LED OK at low lumens
• Pressure: no stacking, no leaning
• Container: archival sleeve + holder + sealed storage box

Avoid:

• Attic (heat extremes)
• Basement (humidity swings, flood risk)
• Direct sunlight (UV bleaches inks)
• Sealed plastic bags (humidity trap)
• Metal containers (corrosion potential)

Failure modes by environment

1. Heat (>85°F sustained) → laminate warp, cardstock dehydration
2. Humidity (>60% sustained) → mold, foxing, paper distortion
3. UV (sustained sunlight) → ink fade, especially yellows/reds
4. Pressure (stacking) → corner damage, slab cracks
5. Temperature swings → micro-cracks in laminate, sleeve degradation

Recommended storage solutions

1. Dehumidifier in storage room (target 40-45% RH)
2. UV-protective acrylic display cases
3. Pelican cases for travel + long-term storage
4. Slab-specific BCW slab boxes
5. Safe deposit box for premium ($1K+) cards
