Next Gen Kid's Tumblers! These are the ABSOLUTE BEST!!!! Designed right here by The Herd and manufactured just for us! They are spill proof, easy to clean with only 2 parts (the cup and the lid), easy to put back together, and keep the drinks cold for those babes! These have the pop top lids on them with the straw so they're easy to use and snap close to keep the spout from being exposed.
