Review on 🚰 Pack of 4 Collapsible 5L Water Tank Containers - BPA Free, Lightweight, and Space-Saving Plastic Water Carriers for Outdoor Activities like Sport, Hiking, Camping, Riding, and Mountaineering - Clear by David Romo

This was exactly what I needed for my cross country trip. I filled 3 of them with tea and froze them. They thawed slowly so the tea stayed cold without taking up space in my fridge. The only problem I have is caps. I'm not exactly sure why they are sealed the way they are. Once twisted, it's almost impossible to break the seal. I had to use scissors to cut it off. Luckily I brought a pair. I recommend removing the seal before use so you don't have any problems on the go or where to take them.
