The super cute koalas sold me on this collection, in addition to the fact that proceeds go to a wonderful cause! This was probably the most varied collection of scents that I've ever had from FCS. Koolah was the favorite of my entire family, from the kiddo to the hubs, and Kanga was a close 2nd! We never all agree on scents lol ;) Koolah smells almost identical to a stress relief eucalyptus spearmint type scent. Kanga is difficult to describe but is the perfect scent for a room/linen spray.
