Buying Guide

- Access method: Choose between key locks, digital keypads, and combination locks based on convenience and desired security. Consider backup access options.
- Capacity and layout: Assess interior space, shelves, and compartments. Multi-layer organizers are helpful for organizing documents, photos, and small valuables.
- Portability vs. permanence: Small portable boxes aid in moving valuables during evacuations, while larger safes are better for dedicated home storage and office use.
- Durability and materials: Fireproof and waterproof boxes use materials like reinforced steel, heat-resistant liners, and robust zippers. Check for water submersion ratings and seal quality.
- Alarm and sensors: Some models include active alarms or door sensors. Decide if an audible alert is worth the added cost for your setting.
