Nothing is more frustrating than opening a storage unit and finding your favorite leather jacket or collectible warped or faded.

Likewise, at home, giving preference to a cool, dry place that is not exposed to direct sun will help your leather and collectibles to remain in great condition.

 

Use Proper Storage Materials

Choosing the right materials can protect your leather and collectibles from heat, moisture, and accidental damage. Here are some tips to make sure your items stay safe and in great shape:

Small fans, ice packs wrapped in cloth, or portable air conditioners can help lower the temperature around sensitive items. Just be careful not to expose items to direct moisture while cooling them.
