The scour is also nearly 1cm in thickness. This very dense, thick nylon will last many cleans.
It's also got a softer touch so it wont damage your fingertips during use, and an inbuilt antibacterial agent that resists the growth of bacteria, keeping away bad smells.
The hole in the middle is for the easy hang storage system.
In the start pack you get one Easy Hang Holder and three scour pads, and in the refill pack you receive five scour pads.
