“I have a SiliPint tumbler I got at a local coffee shop - I love it. I wanted to see if I could find a sip lid on their website and I did. I also found this little treasure of a cup for my little grandson. It isn't 100% spill proof however he can practice his drinking with a straw and sipping when he's in the mood and I don't leave him unattended with it so he's learning his limits. He has figured out how to use it pretty easily. Great product & I highly recommend it.”
