Hi Beth,
Thank you for reaching out and sharing this concern with us! I apologize for the confusion and the warped straws. All of our glitter straws are handwasher only and should not be placed in the dishwasher. Any straws that do not have the glitter included would be dishwasher safe. If you are ever unsure, we do share that information under our Care + Use section of the product page.
Please reach out to us via email with photos of this concern and we would be happy to see if there is anything we are able to assist you with further!
Best,
The Swig Life Team
