Supra Portable Combination Keybox Lock Box Resettable Push Button

 
It shows signs of age and use, but is in good functional condition. The lock box is designed to store keys and small items, allowing anyone to enter that has the proper combination. It hangs easily on a doorknob, fence, railing or pipe. Just open the lid, lift the shackle and hang it up; no tools are necessary. It is constructed of sturdy metal with a protective rubber cover, and designed to be used outside. You can change the combination easily and as often as needed. It uses a 4-digit combination.
 
I used it for rentals, so I didn't have to keep up with keys to be able to show them between tenants, and it worked really well. If I needed to have work done by an outside company, I could give them the combination and then easily change the combination afterwards. (BC)
