Hydro Flask lunch box. Zippers work just perfect as they should. Handle is perfect as well. Has kept my blue ice block frozen for 10-12 hours. Food is still cold at the end of the day. I just have too many lunch boxes. Smoke free, pet (dog) friendly home. Make me an offer, but please no low balls. I am likely to decline them. Please reach out for any questions, and have a wonderful day!
