Players on Roblox can buy virtual items from the Catalog using virtual currency. This currency is obtained by selling items on Roblox or logging in daily if a player has a Builders Club. There is only one currency as of 2016, Robux (R$), which can only be obtained by purchasing Roblox Premium membership, uploading gamepasses or clothing, buying a Robux card from certain shops, or using a credit card or PayPal on the Roblox website. Robux is used to buy items such as Gear (tools to use in-game such as swords) and Hats. On the Character page, players can change their clothing and customize their character as they please. All the virtual items that a player bought from the catalog appear here. Roblox sometimes gives away free items during special events.
