Endure 9 oz. Tritan™ Plastic Stackable Rocks / Old Fashioned Glass - 12/Pack

We don't own a restaurant but we have 5 kids (ages 1-10) and they love these cups. We can feel better about giving them "unbreakable" cups that aren't made of cheaper, toxic plastic. They are relatively light but wear more weight down at the bottom which helps them not tip over, often. These stack well and have yet to break. We bought one set a couple years ago and bought another since we go through cups quickly. The first batch is still holding up well and we have yet to break any. They have gotten a bit scratched up and you can tell the old from the new, but they are holding up to the abuse of my kids pretty well! Only negative is that both times when we've gotten them, there are little plastic squiggles form the manufacturing process (when they cut or trim the cups) that are in the packaging and inside the cups. But we just open over a box or the trashcan and wash each with soap and water thoroughly before using. So hardly a negative. Just something to be aware of! Would and will definitely buy again.
