A dispenser includes a flexible outer tube, a flexible inner tube in the outer tube, a plunger switch, a spring biased valve assembly having a rotation actuator, and a cap. After cap removal, a rotation of the rotation actuator enables an extrusion of a material in the outer tube out of the spout of the valve assembly via a material dispensation tunnel of the rotation actuator when the outer tube is depressed. A further rotation of the rotation actuator enables an extrusion of a material in the inner tube out of the spout of the valve assembly via the material dispensation tunnel when the outer tube is depressed. A still further rotation of the rotation actuator enables a mixed extrusion of the materials in both the inner and outer tubes out of the spout of the valve assembly via the material dispensation tunnel when the outer tube is depressed.
