Generally, people have a difficult time to knowing how much they should spend the amount of washing liquid when they wash dishes.
As a result, people use more washing up liquid than needs and it leads to water pollution.
To indicate proper amount of washing up liquid, we considered to design the shape of scourer.
Not having simply flat surface but having a hole in the surface, intrigues people to pour washing liquid into hole, and it has identical volume with the proper amount of washing liquid.
The shape of the hole comes from a shape occurred when people spill washing up liquid at scourer.
