I used to put the mats on the rack above the washing machine, but I was worried about how it looked, so I bought this. It might be hard to see in the photo, but it's a cute pink color. I wanted to put it in a place where I would use it often, but I also wanted to hide it. With this, you won't even notice that there are mats in there at all. We use different colors and sizes of N-in-box so that the people using them can tell them apart. This is a good way to use them because there are lots of different colors and sizes. It's also nice to have everything in the same series so it looks neat!
