I brought 2 of these cups- one for me and one for my little one. We love to go out for juice and smoothies and are trying to reduce our plastic. They look gorgeous and kept our drinks cool whilst we were out and about. No drips or spills and easy to clean.
Montiico Stainless Steel Smoothie Cup
Great cup for thick drinks as described. My son still likes to pull the straw out as much as he can until it gets to the stopper, but it's still a great design.
