The Best!

We now have 4 sets of these for our two boys. We bought our first 2 when our oldest started kindergarten 10 YEARS ago. They get used daily.

The bottom container fits a sandwich. The small container is their daily veggie and the rest of the middle container is their daily fruit.

They’ve always left anything they didn’t finish in the box. So, I’ve been able to figure out how much they actually will eat in their lunch and reduce waste.

We’ve also used silicone muffin cups to further subdivide the trays too.

This bento, an ice pack and a 12 Oz Klean Kanteen fit perfectly in their lunch.

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.
