This depository lock box is protecting papers from identity theft prior to pickup for shredding. If it's bolted and not overflowing, safety is reasonable; it mostly prevents a passive casual walk-by "grab" of miscellaneous but confidential papers. The generously-sized "drawer"-style drop accepts labeled empty medication bottles as well, as it's a good reasonably safe storage place prior inking over the labels. It can also pass reasonable security efforts for locked containment and chain of custody when monitored and not accessed. (Refer to your exact requirements.)I would not trust this alone for extended periods, or unsurveilled with cash or jewelry, since it would be priable with little time and preparation or, simply, improvisation. More expensive depository safes have dual custody locks for some accountability during pickup, much thicker walls, and tighter construction necessary for cash and jewelry, etc. In general, the more expensive the item(s), the more expensive comparable security will be. Also, any drop-box is susceptible to anything (destructive or otherwise unintended) that can be "dropped" in. As a temporary holding place for papers prior to shredding... perfect.
