Review by Frazer on 9/1

About a month ago I ordered these (also the mini and XL seal cups) to have an alternative to my Pyrex glass containers, which aren’t leak proof. These have been very useful, and I tend to use at least one when packing my lunches for work. I haven’t had any leaks with the cut fruit and veggies, hummus, or thick stew (I use a bowl at work to reheat) that I’ve had inside. I try remember to grab the large container (orange lid) when I go out to restaurants so I can use it as a take-away container for my leftovers, and it has worked really well for that. All of the containers, including the mini and XL, can nest together with the lids. For storage, I place the lids under their containers as it cuts down on noise when taking them in and out of the cabinet. I have not washed them in my dishwasher, but instead hand wash them so I can use them the next day.

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.
