I've actually done the rubber ball magic item before in D&D 3.5 edition. I priced them out as scrolls that contain only one spell and they turned out to be fairly balanced. Just read the command word written on the ball and throw. For example a rubber ball with a targeted Dispel in it can be thrown at a magic trap to suppress it for 1d4 rounds.

And this is perhaps the greates line ever if read without context.
