Sturdy, contoured handles that make it easier than ever for little hands to get a comfortable grip. One-piece, spill-proof silicone spout valve that makes sipping easy for tiny mouths, and is also removable for easy cleaning. Attached lid stays open when baby drinks and keeps spout clean when not in use. Easy to assemble and clean and is dishwasher safe - 6 ounce /180 ml. Recommended for babies 6 months plus While cup is still in box, we did open it to find that it was a cup we’ve already tried when getting my daughter to transition to a cup. Cup has never been used.
