My kids go through cups like CRAZY!!! I don't like using glass because- hi, 5 kids. I feel like my house is being overrun by plastic. Interesting since there are suspicions and probably even some evidence to link plastic to behavioral issues.
In any case, I decided these Stainless Steel tumblers by #Maxam would be a cool thing to review, so I did! They are small, so perfect for my kids. They sound like steel. There were some concerns on the reviews on Amazon, but I don't know if they actually bother me or not.
In any case, here are the tumblers. I made a YouTube video where you can see them closer and hear them.
