Is the storage box truly waterproof?

Yes, the resin construction creates a waterproof seal that prevents rain and moisture from entering. The lockable lid adds an extra layer of protection.

Can I use this indoors?

Absolutely. While designed for outdoor use, its durable construction and clean black finish make it suitable for garages, basements, or utility rooms.

How do I maintain the storage box?

Wipe it down occasionally with mild soap and water. The UV-resistant finish requires minimal maintenance. Store with the lid open in winter if you live in very cold climates to prevent moisture buildup.
