Around and around the sachet goes, tumbling in the dryer with your damp clothes! What comes of this tumbling (in addition to the gorgeous scent wafting from your dryer) is clean-smelling, lightly fragranced duds. There are 3 sachets in a bundle, each good for 5-6 washes. Use in the traditional manner to freshen drawers, gym bags, any storage area. Great stocking stuffer for students!
