Another use for the Scrap Box is by right-clicking while holding it in your hand to yield a random item. You may also place them into a Dispenser, Deployer, or Scrapboxinator for the same result, allowing you to automate this process.
You can get a variety of items based on their drop rate chance. A diamond for example has a 0.02% chance of dropping from a Scrap Box.
