Was looking for a fireproof document case and found this. Ordered and arrived very quickly. Case is large enough for ISO A4 sized documents. The case feels sturdy and well made. This is not a safe but it is lockable. This was purchased to hold household documents and protect them from fire and water damage. The rating for this is ONE hour as noted in the documentation; this is an F series product. The H series is rated for 30 minutes only.
