### ⭐⭐⭐⭐⭐ Great cup
*by C***N on March 10, 2026*

Very durable and holds a lot of beverage. The paint seems to hold up well to being washed. Update since last review. I just want to say the manufacturer, Bioworld merchandise is an awesome company. My daughter's cup was knocked off from a shelf and the lid and straw was broken. I couldn't find a replacement lid for the cup so I emailed the manufacturer. They replied within 24 hours, and they're either going to ship a replacement lid and straw or maybe a replacement cup. I'm not sure on the details other than I was told they would take care of the issue and requested an address.
