Functional!
I bought these after moving into our new home with hardwood floors. These do a great job of collecting water, dirt, mud and all other junk you might bring in from outside that you don't want tracked on your floor. Shipping took forever, which is why this product gets 4/5 stars. I found something identical at Bed Bath & Beyond (for $7.99) after purchasing these on Amazon. Will buy them at a store next time as shipping just took way too long for me.
Rating: 4 stars
