Hi Juliette 1227, Thank you for sharing your experience with the Bentgo Chill Kids Lunch Box and thank you for being a loyal customer! We’re sorry to hear about the leaking and food mixing when stored vertically—that’s certainly not the experience we want for you. While the box is designed to be leak-resistant with thicker foods (like yogurt or dips), it performs best when kept flat in a lunch bag. For vertical carry, we’d recommend exploring our Bentgo Kids Snap & Go or the Bentgo Chill Max XL, which may be a better fit for your needs. We’d love to help troubleshoot with you further and make sure you have a lunch box that works the way you need it to. Please reach out to us directly at support@bentgo.com or call us at 714-668-0300—we’re here to help. Thank you, Jessica Bentgo Customer Support
