Buffalo Coin

If you are not familiar with cryptocurrency, paper wallets are an easy and secure way to physically store your private keys (the secret code which gives access to any funds on an account.)

There are existing free and trusted services which can be found here:

If you do not trust the website, you can download the open-source javascript and run it offline:

Be sure that you've created a "Litecoin" wallet - [bitcoin wallets will not function properly, and sending funds to them can result in a permanent loss of funds!]
