Abstract: A modular case includes: a base having opposing side rails formed along sides of the base, the side rails forming elongate channels therein; a plurality of container modules removably secured on the base, the plurality of container modules having a base plate having a width extending across a width of the base such that sides of the base plate fit within the elongate channels formed by the side rails of the base, one or more containers formed on the base and extending upwardly therefrom, the one or more containers including an open end, and one or more caps secured to the one or more containers over the open end. Sides of the plurality of base plates slidably engage the elongate channels formed on the base such that the plurality of container modules are removably secured to the base.
