Found the kids' cup that's actually leak-proof — even with the straw open 🙌 My kiddo has been using this daily and it hasn't spilled once, even upside down. It's perfect for back to school and the vacuum insulation keeps drinks cold for hours. Bonus: it's also dishwasher safe. Comes in so many cute colors too — linked here! 🧃 14oz Zak Designs Sutton Siply Tumbler 💧 Leak-proof spout, open or closed 🧊 Keeps drinks cold for hours 🧼 Top-rack dishwasher safe Perfect for school, sports, or on-the-go days.
