Review on Durable and Safe Disposable Smoothies: Your Reliable Reusable Tamper-Proof Solution for Catering by Jeff Figueroa

Although the bottles are mostly sealed and do the job. I was so disappointed after putting them in the dishwasher for the first time. Some of them have shrunk and are now awkwardly bent. Also, the ring that goes on the underside of the lid doesn't stay on, making that part useless. I don't want to return them so I'll just keep them and am dissatisfied/disappointed with how they look now. Whoever decides to buy them, please hand wash them in cold water, or they will be turned upside down like mine. They are not dishwasher safe.
