Made of reinforced plastic with a very good lid closure (gives you the feeling that it has closed securely) where there are no leaks (I filled it up and turned it upside down, holding it for some time, no problem). It is useful for storing and transporting fuel for any occasion. I filled it with fuel almost to the top and stored it in a closet with its fuel for about ten months. Its dimensions and shape allow it to be stored in almost any place. What I noticed was that every time I opened the closet, it had a smell, but not a worrying one. In addition, the nozzle is stored-fixed on the sides. It just needs a little attention when applying the nozzle, that is, not too tight because it will "turn" and not too loose because it will leak. If you find the right "step" in its "locking", you will do your job without any problem. The first time I used it, on the third try, I found the right position for the nozzle and everything was fine, no leaks unlike another one I had before where half of the fuel was lost during filling and it made a mess. Perhaps the nozzle could have been a little longer for more convenience (it is about 30 centimeters).
