Fireproof Document Bag with Lock 5200℉ Heat Insulated Waterproof and Fireproof Bag with Zipper Fireproof Bag Storage for Money, Documents,Passport and Valuables 15 x 11 inches

I have been using these sorts of "firerproof bags" for many years for storing RC lithium polymer batteries. In the RC hobby, these bags are generically called a "LiPo Sack". Such batteries can have a flammably bad day if they are overcharged or damaged. Sometimes the damage isn't visible so it's best to be safe. I keep LiPo batteries inside while charging and while transporting to and from the flying field with my aircraft in my car or truck. I've even had my smaller chargers inside the sack with a battery while charging, with only the power supply leads coming out the corner where the flap folds down.This bag is larger than my other Lipo Sacks. The flap that secures it closed is around twice the length of the others, and so is the hook and loop fastener. This allows the bag to expand to hold more items, thicker items and still be able to close securely. That's been a limit on my other bags, especially with a charger inside, but also as I'm flying larger aircraft that use some seriously large battery packs. The price is comparable to what I have paid for smaller RC Lipo Sacks, but with the larger size it's a particularly great value. On top of that, the quality of the seams, velcro, rounded edges is simply better. It clearly has a sticky/slippery silicone impregnated exterior, much more than others, and a tighter weave fiberglass lining the interior. The silver outside is definitely not silver duct tape but appears to be a flame retardant material. I'm not going to intentionally start a fire inside or outside of it to see how it and the contents survive, but the construction is superior to others I've been using for years.Until I found this Colcase bag, I didn't know that these bags were also used for storing documents to keep them safe from fire. It actually makes sense for that purpose.I did try to fit some documents inside, and am pleased that the large UPS Priority Mail cardboard envelope, thick with all of my tax stuff return inside, fits nicely inside with room to spare for several more. It's a pretty roomy bag to store documents. I actually keep super important stuff in the safe deposit box, but for things around the house, before I get to the bank, I might pick up another one as I intend to use this very nice one for RC batteries exclusively.On top of that, it arrived in 1 day from Amazon. Can't beat that.

Very pleased with this fireproof case. Well made. Hope I never have to test it out. But happy to have it for important papers for safe keeping. I have a fireproof lock box, but this case is easier to store in a drawer or wherever. Large enough for small items also.

These work great for storing my important papers. I like how they have a double closure.Can’t go wrong with this purchase.

Haven’t had any experience yet to see if it holds up. Hopefully I won’t have any reason to see if it works

It's not large enough for paperwork storage. I use it to store coins and cash plus some jewelry. It zips up and has Velcro to seal it tight. I keep in a large safe and is ready for grab and go. great item.

I have a few of these bags. I don’t know how they would hold up in a fire or flood. But they seem sturdy and are great for storing papers, etc in or out of a safe.

Love the idea of a fireproof bag, hopefully won't have to actually test whether they work or not. Interesting how many are rated to withstand higher heat than some fireproof safes. Anyways, nice bag with multiple layers, but unfortunately it was too thin to fit a standard three ring binder of documents. The actual pouch was big enough but the flap was too short to close by about an inch once folder over. Only downside is the flap is just secured by velcro, not sure how well that would hold up during a fire, could see the velcro easily melting and the flap falling open. A more secure sturdy flap closure would be better. Ended up having to upgrade to something a bit bigger and thicker.

Nice and reasonably priced

Ich denke das dass Ding wirklich Feuer abhalten kann. Die Qualität wirkt auf den ersten Blick sehr hochwertig und gut verarbeitet. Möchte es aber auch nicht herausfinden!

Nice product....much needed

Arrived quickly. Has 2 compartments and can actually hold quite alot of stuff in it. Worth the purchase

Arrived in good condition. No visible problems, but obviously am not testing this in a fire to confirm it's protection is as advertised. Will just have to trust them. Fits a decent amount of documents, even some slightly larger than A4 in plastic protective sleeves.Am going to put this in a bigger fire proof case for double the protection in case one fails to protect as advertised.
