Disclosed is a bar of soap having a recess in one side thereof and at least one projection extending outwardly from the recess. At least one opening is formed from the opposite side in alignment with the projection. As the bar of soap is used and portions dissolved, the bar becomes smaller and smaller and the opening becomes larger. At the point when the bar of soap is almost consumed, it will fit into the recess of a new bar of such soap and the opening in the used bar will coincide and engage the projection on the new bar. In this manner, the thin pieces of used soap are pressed into a new bar of soap thereby permitting complete consumption of each bar of soap used.
