A portable floss cup that allows for quick and convenient access to un-used portable flossers is provided. The floss cup is sized to fit in the cup holder of one's vehicle, and may be composed of paper, plastic, or biodegradable materials. The cup is formed with an inner wall for receiving used portable flossers and waste therein, an outer wall having a diameter larger than the inner wall, and an upper wall extending between the inner and outer wall. Un-used portable flossers are radially disposed in slots provided around the upper wall. A lid large enough to cover the top of the cup may also be included. Once the flossers provided with the cup are expended, an end user may either replace the expended flossers with new un-used ones, or they may replace the cup entirely.
