    Great storage option

  2. jon (verified owner)

    case works well

  3. Carlos (verified owner)

    Perfect for when you need extra batteries.

  4. Khan (verified owner)

    Better than throwing your batteries in a zip lock bag.

  5. Christian (verified owner)

    A nifty little battery case; definitely a slicker, more durable option than a plastic baggie. The threads are actually quite fine and the two halves fit together very tight. As others have mentioned, it has an O-ring, and there’s also a disc of cut foam for padding to stop them from rattling. Great for a bug-out bag, day pack, EDC bag, or glovebox. Competitively priced compared to a Thyrm Cellvault or similar options.
