These will open 90% of mailbox's used in apartment blocks, and business parks similar to the ones in the picture.
It also opens alot of filing cabinets and draws that are used in offices; However its primary function is the mailbox's.
This is great if you have lost your key. Generally body corp can charge 100-150 for a replacement :/
The key is also useful if you have multiple properties and do not want to carry around a number of keys.
If the mailbox is a newer grey looking one as seen in the picture their is a very high change it will open. It does not matter if the mailbox is stand alone, a group of 4 like the picture or their is 20 of them next to each other, which is very common in apartment blocks for example.
I wish to sell the keys for $70 (in bitcoins) and I will ship it discreetly to anywhere in AUS or EUR.
