Review on 800ML Disposable Urinal Bag For Travel, Emergency Portable Pee And Vomit Bags (12 PCS) By DIBBATU - Unisex Urinal Toilet Bag Suitable For Camping, Traffic Jams, Pregnant Women, Patients & Kids by Cameron Chandra

These bags are easy to use for a guy. Not quite sure how it works for a girl though. Opening is quite big, and it has a zipping mechanism that works quite well. Have tested a bag by filling it with water, seal it and flip it upside down to test. It doesn't solidify the liquid like some name brands do, but it doesn't cost as much either. To me, as long as it seals and doesn't leak, it does it's job. However, since the liquid is still liquid, I would not pack it with things that might put pressure on the bag after being used, as I'm afraid it could squeeze out.
