This is a specially designed (in Australia) multi-flexible spray, which you can direct with a light touch of the hand to provide full sink coverage. It pushes so easily onto your sink tap and after use you simply remove it and store it for next use.
It’s great as a pet shower as when in a fixed position it leaves both hands free for lathering. And when rinsing off you just move the flexible spray around to cover all positions.
It has other handy uses in the bathroom and kitchen.
