Its a solid well made cabinet, obviously I can't attest to knowing just how 'fire-proof' it is, and I hope I never have to find out. The lock is decent, helpful that it can be closed and locked without having to use the key. Had originally looked at the larger cabinet but delivery options turned into such a can of worms (only because of my location for delivery) this smaller cabinet was the simple solution for a quick fix (and less of a pain). That said, the sales team were a great help, so thank you John! Delivery team were in and out no fuss.
