This bag contains twenty iron balls, each measuring one inch in diameter and weighing 1/4 of a pound. When poured out of their bag as a Utilize action, the balls function as Ball Bearings.

As a Bonus Action, you can speak the command word, which causes a number of the balls that you choose to expand into full-size cannonballs weighing 10 pounds each, suitable for firing from a cannon. A creature in the path of one or more cannonballs rolling downhill must succeed on a DC 13 Dexterity saving throw or take 2d10 Bludgeoning damage and have the Prone condition if it is Large or smaller.

Each iron ball can also be used as a Sling Bullet or a Firearm Bullet. As a Bonus Action when you make an attack with an iron ball as ammunition, you can expand it in midair. On a hit, this attack deals Bludgeoning damage equal to 2d12 plus the ability modifier used for the attack roll instead of the weapon's normal damage.
