The ultimate watering cans. Inventor and founder John Haws, who perfected his design in 1886, promises "This new invention forms a watering pot that is much easier to carry and tip, and at the same time being much cleaner, and more adapted for use than any other put before the public." Not such a new invention anymore (130 years young) but still the leader in its field. Options available for use indoors, outdoors and in the greenhouse.
