COMMON QUESTIONS
How much can really fit in 40ml? More than you'd expect! 20-30 pills, multiple rings and earrings, 4-6 micro SD cards, or emergency cash and contacts. The cylindrical shape maximizes storage efficiency in minimal space. Will this really survive being submerged underwater? Yes, IPX7 rating means it can handle 1 meter of water for 30 minutes. That's far beyond what most travel disasters involve. It's tested to submarine sealing standards. Can I open this easily with wet or cold hands? Absolutely. The silicone pull-tab is designed for extreme conditions. Works perfectly with diving gloves, ski gloves, or when your hands are numb from cold. No twisting or complex motions required. Is this TSA compliant for airplane carry-on? Yes, 40ml is well within TSA liquid limits (100ml maximum). Security agents recognize the size immediately and won't question it. Perfect for keeping critical items in carry-on luggage. What makes aluminum better than plastic for this? Aluminum won't crack under pressure, handles temperature extremes without becoming brittle, and provides a perfect surface for waterproof sealing. Plastic containers fail exactly when you need them most. How do I know if my items will fit? The internal dimensions are 2.7" x 1.3" diameter. Most small essentials fit easily: standard pills, rings, earrings, micro SD cards, small batteries, folded cash, and contact cards. |
