Does it really protect paper in a fire?

The fiberglass fabric is rated to 1832°F, well above typical house-fire temperatures, and tests of similar bags show paper surviving brief flame exposure. The zipper and seams are less protected, so treat it as extra time, not a guarantee.

Will it fit A4 and letter-size documents?

Yes. At 13.7 x 9.8 inches the interior takes letter and A4 sheets flat, plus passports and cash envelopes. Larger legal-size folders will not fit.

The silicone coating and waterproof zipper keep splashes and brief immersion out. It is not rated for prolonged submersion.

Can I put it inside a safe?

Yes, and that is the best use. The bag adds heat and water protection inside a safe or drawer, but on its own it does not stop theft or crushing.

Is the fiberglass safe to touch?

The coated surface is fine, but cut edges and the interior can shed fibers that itch. Handle with gloves if you are sensitive, and keep it away from children.

What comes in the package?

One black document bag. There is no folder, divider or lock included.

Our take on the Large Fireproof Document Bag

This is a flat, zippered pouch made of silicone-coated fiberglass, sized to hold letter and A4 papers, passports and cash. The material is rated to 1832°F, which is far above the temperatures a typical house fire reaches at the floor of a safe or drawer. It is a soft bag, not a rigid safe, so it protects paper from heat and water but not from crushing or theft. Rivals in this class add rigid shells, multi-layer insulation or larger file sizes; this one keeps it simple and light.
