Fluf Zipper Lunch bags are made with certified organic cotton and and a tested food-safe, water-resistant lining (free of BPA, phthalates and lead), and come equipped with a state-of-the-art security system. Okay, it’s called “a zipper”. But it’ll keep those wily, runaway lunch containers in the bag – where they belong. Guaranteed. Forgot to clean out your lunch bag over the weekend? No worries! Rinse the lining in the sink with soap and water (it dries instantly) and throw the entire bag in the washing machine anytime. It’ll come out smelling like roses.
