Little Trees MTZ04 Air Fresheners Black Ice, 6 PiecesProduct Description LITTLE TREES was first introduced over 60 years ago when a milk truck driver in Northern new York complained to Julius Smann, a local chemist about the smell of spilt milk. Smann spent some time deep in the Canadian pine forests learning about aromatic oils. He went to work and using exceptional fragrances on speciality material soon developed the concept of a hanging air Freshener. The tree design and LITTLE TREES are trademarks.
