Leak-Proof Cups Kids Love

The zak! Kelso tumbler is leak-proof and designed with a silicone sipper spout that has a built-in valve to prevent spills. It's ideal for kids who are on-the-go or transitioning from sippy cups to open-topped tumblers. It also features a detachable spout for easy cleaning and is top rack dishwasher safe.

I wish I knew about zak! designs when I had my first baby. I highly recommend them to all mamas.
