Abstract: A dental floss dispenser which, from a size and shape standpoint, looks very much like a credit card housed within a protective case. The dispenser includes a floss holder which can be described as flat, relatively thin, of a generally rectangular shape, and preferably made of a relatively rigid material. The case for the floss holder completely surrounds the holder and is open or openable at one end so that the holder may be easily moved in and out of its case. The case can be made of a flexible plastic material--with a clear plastic being preferred. The holder is provided with a supply of dental floss which is preferably wound from side edge to side edge of the holder and about the middle section thereof. This leaves the upper end of the holder free of floss. Near the upper end of the floss holder which is the end initially withdrawn from the case and on one edge of the holder is a notch which is used to engage and hold the floss after a length has been removed from the holder.
