Waterproof bags are outdoor storage gear that integrates waterproofing, dustproofing, abrasion resistance, and portability. Made with high-sealing technology and durable waterproof materials, they comprehensively protect your mobile phone, clothing, electronic devices, outdoor tools, and other items from water immersion and mud contamination. They are widely applicable to water sports, outdoor travel, and daily commutes.

三，Usage Precautions

1. Before use, place dry paper towels inside the bag, seal it, and immerse it in water for 10 minutes to test its waterproofness. Only use it after confirming there is no leakage.

2. For roll-top dry bags, roll them up 3-4 times and fasten the buckle to ensure a tight seal. For touchscreen models, avoid scratching the transparent film with sharp objects.

3. When storing wet clothes, it is recommended to first wrap them in a sealed bag to prevent moisture from seeping into other items.

After use, rinse the surface with clean water to remove dirt and salt, and air dry in a ventilated place. Avoid direct sunlight or high-temperature baking.
