One sisal soap bag measures approximately 3.5"x5.5", and comes with a convenient draw-string to hold your soap inside, and allows you to hang up to dry between uses. Made of natural sisal fiber that comes from the leaves of the agave plant, the fibers provide gentle exfoliation and produce more lather. Large enough for most bars of soap, but also holds the last bits of leftover soap that are too small to hold, abling you to use every last piece. (Soap sold separately)
