Haws started making watering cans in 1884 .... that's a long time to have been refining designs and manufacturing.
Still made in England.
We've selected the outdoor watering cans that we use. The two smaller plastic ones (The Sutton Splash and The Selly Soak) live in the green house.
The metal Bearwood Brook 2 gallon handles watering the pots and beds during the summer and the 1 gallon Warley Fall keeps the beans green on the veg patch.
