A modular storage system includes a number of receptacles and lids with different sizes and features that are interchangeably coupleable to each other in a stacking arrangement. A first lid has slits to provide access to a receptacle and a second lid has a suction cup and is structured to be interchangeably coupleable to the receptacle and the first lid. A user can remove the second lid from the top of the first lid and secure the second lid to the bottom of the receptacle with the suction cup secured to an external surface. A third lid includes an opening covered by a deflectable membrane. The membrane prevents liquid from spilling from the opening if the receptacle is knocked over. A straw can be inserted through the membrane and opening to provide further functionality.
