Mom Owned

This brand is created, owned, and run by a mom (or several moms). Celebrating mom-owned companies is necessary given the incredible efforts moms make acting on the source of their motivation and values through parenthood and entrepreneurial creation.

Women Owned

This brand is owned by a majority of women. This includes everything from a small one-woman shop to a larger company where more than 51% of women make up the ownership team.

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.

That means less waste on the environment, and a healthier, non-toxic lunch for you!

    This box is perfect. This box, along with the splash boxes, are my go to for days out bouldering. It slides into my bouldering pad and doesn’t leak. It’s hard to lose because it’s so shiny. So far it has been a wonderful companion for long days outside. The tiny splash boxes fit inside easily and allow me to compartmentalize my meal if need be.

    Just what i was looking for

    I was afraid it would be too small but my sandwich and fruit fit perfectly with enough room for a bagged snack, if I want to include it. It’s also thicker metal than I thought it would be! Very substantial and shiny pretty, too!

    Great size and quality

    cummingskacie (verified owner)

    I was worried this would be too big, but it seems to be the perfect size for takeout food like I was hoping. The pictures make it look bigger than it is. Product is great quality, and the clasps on the sides are spring loaded so it’s super easy to open/close. So glad I bought this!

    Will work well for me. Using it for a first aid box. Wish it was a little larger.
