Apparatuses, such as massage rollers, for partially enclosing a rotatable spherical object are disclosed herein. A massage roller may include a housing formed from a base and cap that, when coupled together, partially enclose a spherical object. The spherical object, such as a stone, of the massage roller may be rubbed on an individual to provide a massage. As the massage roller is rubbed onto the individual, the spherical object may rotate within the housing.
