I have been using Stasher for a while now, I love the fact that they reduce my plastic usage and that they are extremely durable. You can cook in them, store almost anything and use them in the dishwasher. They the perfect solution for someone who wants to reduce plastic and they last. I have never had problems with them and the one time I did, I emailed them about a rip in one of my bags and they responded promptly and sent me another bag. The bags and customer service is top notch! I love my Stasher bags and will continue to support them.
