Sachet

Although its most usual definition is that listed under "packet" (see link above), a sachet (/ˈsæʃ/ sash-ay) can also mean a small scented cloth bag filled with herbs, potpourri, or aromatic ingredients; or a small porous bag or packet containing a material intended to interact with its atmosphere; for example, desiccants are usually packed in sachets which are then placed in larger packages. Cotton, linen or organza are used to create the bag.
