Great for daycare
Review by Emily on 3/21
Great for daycare

Our daycare won’t take glass containers, so we were trying to find plastic alternatives for packing lunch. This little container is great. We pack overnight oats in it and never have leaks. I also love the silicone top, as most containers have plastic tops.

About Eco LunchBox
ECOlunchbox was born of the idea that change can begin at lunchtime. I wanted to make a change in how I packed my family’s lunches – to cut out the plastic and do the right thing for our health as well as Mother Earth. It seemed like a pretty simple concept. Design a food container out of something plastic-free and make it available to friends, family and through an online store. Since founding ECOlunchbox as a triple-bottom-line social enterprise in 2009, the business has scaled beyond my initial vision.
