Bag of Cement

Usage
The Bag of Cement is used to cover up Tunnels from the inside or the outside. Note that it will only cover up the Tunnel, because if you dig again the Tunnel will remain and will contain all of the items inside of it (if any items). Using the Bag of Cement is a good strategy for storing Contraband. It's very difficult to find inside a prison because it is a rare item.

Obtaining
The Bag of Cement can be bought from fellow inmates, found in their passed-out body or inside their desks.

Trivia
In the Alpha Version (0.792), the Bag of Cement could be found very easily. Every inmate with a golden bag over their head sold a Bag of Cement at very low prices.
