Why Storage Conditions Matter
Vinyl degrades under UV light (yellowing, brittleness over years). Paint fades under direct sunlight. PLA softens above 60°C. Humidity above 70% promotes mold in packaging. None of these happen overnight — they accumulate over months.
If you're storing a figure you plan to resell, condition is everything. Even a 2-year-old figure stored incorrectly can show yellowing or paint fading that tanks the resale price.
Temperature: The Key Variable
Ideal storage: 60–75°F (15–24°C). Avoid attics (can hit 130°F in summer), garages (temperature swings), and basements (humidity). A climate-controlled interior room or closet is ideal.
For PLA figures specifically: anything above 140°F (60°C) risks deformation. Summer car interiors easily hit this. Never leave a PLA figure in a car during summer months.
Light: UV Damage is Real
Direct sunlight will yellow white/cream vinyl over 6–12 months. Even indirect bright light causes slow fading. If you want figures on display, keep them away from windows, or use UV-filtering window film.
Enclosed display cases provide some UV protection. Glass with UV coating provides more. If long-term value preservation matters, dark storage (closet, storage box) is better than even indirect light display.
Packaging for Long-Term Storage
Original Pop Mart box is best — designed to hold the figure without contact pressure. If the box is gone: acid-free tissue paper wrapped loosely, placed in a rigid cardboard box, with silica gel packets to control humidity.
Do not use plastic wrap directly on vinyl — certain plastics off-gas chemicals that react with vinyl over years (plasticizer migration). Acid-free tissue only for contact packaging.
For 3D Printed PLA Figures
PLA has a glass transition temperature around 60°C — significantly lower than vinyl. Temperature control is more critical. Same UV sensitivity (depends on paint type). Moisture: PLA is slightly hygroscopic but painted surfaces seal most absorption.
Labubu Studio ships in a protective carton. Keep the original shipping carton if you plan to store the figure — it's designed for the figure's dimensions and provides foam-cushioned protection.
Inventory: What Collectors Often Forget
If you have multiple figures, photograph each one before storage — front, back, base, with ruler for scale. Date the photo. This creates a condition record that's invaluable for resale or insurance purposes.
A simple spreadsheet: slug, purchase date, purchase price, condition notes, storage location. Takes 5 minutes per figure. Pays back when you sell years later.
