WORK MAN Vacuum Hybrid Container from Workman. I bought this to put ice in for camping, but since I don't drink alcohol, I didn't find it necessary to bring it just for ice, so it ended up unused. I used it during a summer camping trip, and the ice remained solid the next day. Separating it from the food cooler box was a good way to prevent it from melting too much. As a bonus, I'll include two ice packs (350g each). I've used it once, and it looks clean at first glance, but it has some scratches because I put it on the ground at the campsite. Please check the photos for details.
