Review: Fantastic Toddler Cup – Durable, Leak-Proof, and Adorable! - The Zak Designs Kelso Tumbler Toddler Cup is hands down one of the best sippy cups I've ever purchased for my little one! The 12oz size is perfect—just right for keeping drinks at the right temperature without being too heavy for tiny hands. The vacuum-insulated stainless steel design is impressive. It keeps my child’s drinks cold for hours, which is especially great for long car rides or days out. I also love that it's completely leak-proof. We've tried so many cups that promise no leaks but still end up with spills. This one actually delivers! Even when it gets tossed around or turned upside down, it stays sealed tight. The "Happy Fruit" design is adorable and colorful, which my toddler absolutely loves. The cup is also easy to clean, with no small parts that can trap dirt or mold. The durable stainless steel construction has held up well to all the drops and throws—it still looks as good as new after weeks of use. Overall, this sippy cup is a winner in my book. It’s durable, effective, and fun for kids. I highly recommend it to any parent looking for a reliable and cute cup for their little one!
Review: Great cup - Our go to cup for my 2.5 year old. She got it last Christmas and luckily I filled it before she got it as she wanted to drink out of it straight away. Great to find one that isn't all plastic. Easy to clean compared to other straw cups so that mould doesn't start growing.
