Who needs just one produce bag? Do yourself a favor and buy this set now, instead of coming back later. With three sizes (small, medium, and large) you'll be a sustainability goddess (or god) on your next produce run. DIMENSIONS: Small: 8" X 10" Medium: 10" X 12" Large: 12" X 15" Why cellulose? Our Birla Cellulose is made from renewable wood sourced from sustainably managed forests, and is 100% biodegradable ( just like our 100% cotton bags). Birla uses a closed-loop process and environ mentally efficient technologies that recycle raw materials and conserve natural resources. While we stand behind our 100% cotton line - as a 33 year old company we believe it is important to change with the times and utilize new sustainability techniques, and are super stoked to now be offering Birla Cellulose.
