Quick answer: Store miniatures indoors in a stable room. Avoid lofts, garages, sheds, hot cars and sunny sills. Steady moderate humidity beats sealed damp boxes.
Why climate matters
Heat softens glue and warps plastic. Damp invites mould on foam. UV fades paint. Practical “where not”: where not to store.
Full storage system: storage hub.
Silica gel
Useful in closed plastic boxes if you refresh sachets. Do not invent a perfect RH number without a meter — aim for “not steamy, not bone-dry attic”.
Frequently asked questions
Is a wardrobe OK?
Usually yes if the room is lived-in and dry.
Basements?
Only if dry year-round; many UK basements are not.
Display cabinets and sunlight?
Keep cabinets off direct sun.
We do not publish a single “safe” humidity percentage — room conditions vary too much. Prefer stability: a heated indoor room with ordinary airflow beats a sealed tub in a damp shed. If windows run with condensation, do not store painted models against that wall.
