Review: Great prduct - This was so cute. I bought it for my water and it keeps it cool
Review: Love this - This is such a great cup for my little one. I love the silicone straw. Keeps drinks cold for a long time. Is NOT leakproof if turned on side/upside down, but I do not believe it is meant to be. It is great though bc if knocked over, it doesn’t immediately spill everywhere.
