A ball case for storing and organizing gage balls of a plurality of predetermined sizes. The ball case has a housing including a base member having at least one and preferably three sloping surfaces. A plurality of partial spherical cavities are formed in the base surface for engagement of the gage balls, the cavities being proportioned appropriately such that a single predetermined horizontal plane above the base member is tangential to each of the gage balls.
