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.

  • Microwave safe, sous vide machine safe, standard oven safe, and boiling water safe up to 400F

    How do you clean it? I am considering buying one but I am afraid that the corners will be hard to clean and that it will get dirty or mouldy.

      Hello! Great question. Those bags are dishwasher safe, and that works well to clean out those corners! We just recommend separating the opening using the dishwasher prongs 🙂

    5 out of 5 I LOVE stashers


    I have 9 or 10 stashers and am absolutely obsessed with them! I use them for everything and they are so versatile!! It’s awesome that they’re microwave safe, oven safe, endlessly reusable, dishwasher safe, the list goes on and on. I wish even more people knew about them because they are such an amazing product!! I have spoken with the company and the people who run it are so kind and caring and overall the company is just great. They’re a little bit of an investment but oh so worth it!! I recommend them to all my friends and family because they’re THAT GOOD.

    5 out of 5 Makeup Bag meets Takeout Bag meets Travel Bag

    AdminJuliet (verified owner)

    Stasher bags are usually known for their ability to cook/freeze/microwave/and store food, but I actually fell in love with my Stasher bag for a different purpose! I travel often, and need to bring my makeup different places. In the past I’ve used cotton makeup bags, but almost EVERY single time my makeup/toothpaste would spill and stain the cotton bag.
    After I heard that Stasher bags are dishwasher washable, I immediately fell in love. I now pack all the spill-y, goopy products in two sandwich Stasher bags, and go! If anything spills, it doesn’t make it out of the bag, and all I have to do is throw it in the dishwasher. Plus, the clear, thin bags are perfect for TSA-Checking at the airport, and make it easy to distinguish between the makeup bag, and the toothpaste/skincare bag when I’m in a rush!

    5 out of 5 Obsessed with my stasher!

    AdminEarthHero (verified owner)

    Becki from EarthHero here–I bought one of these the moment we received them at our office and I absolutely love it! I love that it flattens out and can fold up in my purse–it has already helped me say no to multiple styrofoam or plastic take-out containers. Plus, it’s super convenient to pop the whole bag in the microwave to heat up leftovers (especially on road trips so I don’ t need to eat gas-station snacks). The silicone is really easy to wash and the amethyst color is adorable.

      I wish you’d show a picture of the opening of these as well on your site. How do they open? Is it a lid or a Ziploc type of closing??

      Hey Nancy, great question! We just added another photo to the product page above, you can see how the bag opens by clicking on the third photo. These bags have a similar zip system as traditional ziplock bags, just made from silicone! We’ve tested the seal by filling it with water and shaking the bag upside down and it held tight. Hope that helps!
