Small airtight waterproof storage box designed to keep small valuables dry and protected during outdoor activities. Key benefits Keeps contents dry: 3 mm PE inner lining and airtight closure limit water intrusion so matches, small electronics, documents, and other items stay dry in wet conditions. Floats for added security: the box will float on the surface if dropped in water. Not submersible—do not dive or fully immerse the box, as it will leak if submerged. Durable protection: impactresistant plastic construction and a tightseal design protect gear from shock, abrasion, and environmental wear during rugged use. Lightweight and compact: measures 135 x 80 x 40 mm and weighs about 50 g, making it easy to carry in a pack, pocket, or boat storage compartment. Features Material: sturdy plastic exterior with a 3 mm polyethylene (PE) inner lining for moisture resistance. Seal: airtight closure that reduces the risk of dampness from splashes and humidity. Colors: available in black, orange, or tan to suit visibility or discretion needs. Capacity: sized for small valuables such as matches, keys, SD cards, compact flashlights, small batteries, earphones, and similar items. Practical use scenarios Boating or fishing: store matches, a spare phone battery, or important keys in the box. If dropped, the container will float, giving time to retrieve it—do not rely on it for underwater protection. Camping and backpacking: keep firestarting materials, memory cards, or medication dry in wet weather or damp ground conditions. Festivals and travel: protect small electronics, cash, or receipts from rain and accidental spills while you move through crowded or unpredictable environments. What it solves Prevents moisture damage to small, sensitive items without adding significant weight or bulk. Reduces the risk of losing items to water by floating if dropped on the surface. Provides a compact, reusable solution for organizing and protecting gear in a variety of outdoor settings.
