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.

B Corp

The B Lab is a third-party, non-profit organization that certifies companies as socially and environmentally responsible. B Corps are businesses that go above and beyond traditional business models and aim to create positive change in the world through their practices. These companies must meet rigorous transparency and accountablity standards, while doing what is best for people and the environment.

Safe and Fair Labor

We support safe and fair labor practices when producing sustainable products. This company cares for their workers by fostering a safe work environment and providing their employees with fair wage.

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.

The Three-in-One is crafted from 100% high-quality, food-grade stainless steel. Note: tRead Morehe locking lids in this product are not leak-proof. To store dressing and dips, the Seal Cup Mini (available here) will easily nest in the upstairs of this set.

    Great lunch box!!!

    luciaesperanzajd (verified owner)

    It’s a little small, but it was built with durable stainless steel. I think that it will last me a long time since the quality is premium.

    Good size lunch box

    leonawade6 (verified owner)

    I got this for taking leftovers home and/or when I am going out and want to bring something to snack or eat a good meal. I got this along with the Tiffin containers for a little more versatility or if I want to pack something extra for my bf when we are out.

    I can’t say I’ve used it yet, but everything came intact and I’m so excited to be able to use it. As someone on their way to college this coming fall, I want to start early with my eco-consciousness in any way I can and this will do the job!

    No more plastic take aways!

    mariana.m.hill (verified owner)

    I love carrying these in my bag everywhere I go. If we have leftovers from a restaurant these are perfect for them! No more plastic take out boxes! Can’t put liquids in there (probably the only downfall), but we have another canister for that. Would recommend

    Space saving lunch kit

    kwyjibo4 (verified owner)

    Love this steel lunch box! It is well made, sturdy, and I love the multiple compartments rather than lugging around a bunch of containers. The small one is perfect (even for adults) for tucking away in your backpack and not not taking up to much space. Keep in mind not to put any liquidy food and it will serve you on your waste free journey well.

    Best compact take out food box!

    Ladyphilosophy100 (verified owner)

    I used to be the crazy lady with a million containers in her bag whenever she’d go out to eat, but now I just carry this one and a leak-proof canister! I am always impressed at how much food fits in here. I love that this one can go directly in the fridge. Many of my containers are insulated, which can be a great feature most of the time, but its a little inconvenient if you just want to stick your leftovers in the fridge. This is one of my favorite zero-waste items!
