ONEDONE Male Urinal Portable Pee Bottle Toilet 2000 ML for Hospital Home Camping Car Travel (White)

This is the only 2000 cc (2 liters) urinal that I could find on Amazon. I have no complaints but be aware that the is not watertight and does not seal. Also, the volume measurements on the side are difficult to use. First of all, it should have a flat bottom so you can set it down to read the volume without wondering if you have it tilted . Also, it would be nice if there were 100 ml/cc marks on the side. The marks are at 125 mL which makes it more difficult to determine the volume.
