Review on Fireproof Battery Organizer Storage Case: Waterproof & Explosionproof Safe Bag Fits 210+ Batteries - With Tester BT-168, Carrying Container Bag For AA AAA C D 9V Lithium 3V Holders by Brian Lee

A nice product. Worth the money. I made an "unboxing” style video that shows exactly how the product arrives. I made another one showing it full.The product sort of looks like it’s made of a textured nylon-like Codura-type nylon. It’s more a rubberized vinyl. I’m sure it’s what makes it "waterproof.” Definitely seems like a waterproof material. It’s not fireproof per se but would definitely prevent the batteries from contacting each other and starting a fire.Foam inside seems robust and like it will maintain shape well. Battery tester seems to work and seems useful. Delivers what it promises . a way to organize your batteries.
