A container comprises a primary compartment, an auxiliary compartment, and a hinge. The primary compartment includes a principle wall, a first lateral wall, and a primary compartment opening opposite the principle wall. The auxiliary compartment includes a first wall and a second wall extending away from each other, and an auxiliary compartment opening extending between the first wall and the second wall. The hinge rotatably couples the primary compartment to the auxiliary compartment such that the auxiliary compartment is rotatably between an open position and a closed position. When the auxiliary compartment is in the closed position, the auxiliary compartment opening faces and is substantially covered by the first lateral wall.
