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.

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.

    this was my first time purchasing stainless steel tupperware as my family has always used plastic and oh lordy am i in love, super easy to clean, surprising light weight, and no smell of strong foods or coloring from things like curry! the lids are silicone and i little hard to get off but the seal is great! i’ve only washed them by hand as i don’t have a dishwasher so i can’t attest to that but overall really great alternative to plastic or heavy glass!
