Modular cosmetic case systems and methods

A modular cosmetic case, comprising:

• a cover having a first lateral side and a second lateral side, the first lateral side of the cover having a plurality of protuberances;
• a housing having a first lateral side and a second lateral side, the first lateral side of the housing having a plurality of protuberances and a plurality of slits;
• and
• a base having a first lateral side and a second lateral side, the first lateral side of the base having a plurality of slits,
• wherein the first lateral side of the housing comprises a longitudinal slot and a protrusion on the longitudinal slot, the protrusion defining a central longitudinal axis,
• wherein the first lateral side of the base comprises a longitudinal slot and a protrusion on the longitudinal slot, the protrusion defining a central longitudinal axis,
• wherein the plurality of protuberances of the first lateral side of the cover engage the protrusion of the first lateral side of the housing,
• wherein the plurality of protuberances of the first lateral side of the housing engage the protrusion of the first lateral side of the base,
• wherein the plurality protuberances of the cover respectively engage the plurality of slits of the housing when the cover and the housing are in an open configuration relative to one another, and
• wherein the plurality of protuberances of the housing respectively engage the plurality of slits of the base when the housing and the base are in an open configuration relative to one another;
• wherein the plurality protuberances of the cover do not respectively engage the plurality of slits of the housing when the cover and the housing are in a closed configuration relative to one another, thereby permitting the plurality of protuberances of the cover to slide along the longitudinal slot of the housing and relative to the central longitudinal axis of the protrusion of the housing, and
• wherein the plurality protuberances of the housing do not respectively engage the plurality of slits of the base when the housing and the base are in a closed configuration relative to one another, thereby permitting the plurality of protuberances of the housing to slide along the longitudinal slot of the base and relative to the central longitudinal axis of the protrusion of the base.
