BPA Free
Products that are labeled as BPA free do not contain Bisphenol A, a chemical commonly found in plastic products. Studies on BPA exposure have shown that high levels of BPA could lead to hormone disruption, effects on behavior and brain function, reproductive problems, breast cancer, heart disease, infertility, and more.

Phthalate Free
Phthalates are found in toys, electronics, personal care products, plastic wraps, containers, and more. These petroleum based chemicals help soften plastics, and bind fragrances to perfumes, deodorants, creams, and other personal care products. Phthalates are are not chemically bound, meaning they can easily get released into the air, water, or your body, just by using the products as intended. Phthalates have been found to disrupt the endocrine system, which can cause reproductive damage, hormonal imbalances, infertility, mood changes, metabolism changes, and more.

ECOlunchbox believes in a simple concept: nutritious and delicious lunches should be packed in non-toxic containers and fill your bellies, not the garbage can. With their collection of dishwasher safe, stainless steel food storage containers and cotton lunch bags, it's easy to ditch the plastic tubs, one-time baggies, yogurt squeezers, and wrapped snacks. That means less waste on the environment, and a healthier, non-toxic lunch for you! Founder and mom-on-a mission, Sandra Ann Harris, believes that the best way to reduce waste is to not create it in the first place. By offering reusable alternatives to everyday lunchbox items, ECOlunchbox helps people to move beyond using plastics, one meal at a time.

Just what I wanted!

Exactly what I was looking

Exactly what I was looking for. I was looking for a leak proof but also easily cleaned container to bring in my lunch that wasn't glass. This fits the bill and I use it regularly.

Krys s.

Trying to figure out the size on this was misleading, I thought I was getting something maybe %50 bigger and can't believe this is a medium, small, sure, but medium seems a bit overhyped. Still, the quality and design are good.


Perfect size for so many things. Easy open/ close, easy to clean, eco-friendly, what more could you ask for?

Minis for Kids' Lunch

I bought some of the minis for my kids' lunches. They are the perfect size to fit inside their bentos with condiments, dressings, and dips. I wholly appreciate that the cups nest together and the silicone lids seal nicely.
