well, I do live in England so the exact same product may not be available to people in other countries.
they are all pretty much the same thing, the screw on lid also has the pump handle on it for pressuring up the container.
some have a pressure valve too but I have seen some without which wouldn't really do the job.
knowing the exact pressure is important.
I would like to add too that doing such things to bring old balls back to life is pretty much pointless if the felt is worn out or is wearing out.
