I purchase 2 of the round version of this rug.  These rugs are not very thick and the picture does not represent them very well, it shows mostly black in fact you can hardly see any white in the picture, the rugs are however approximately 40% white threads.  I bought them to protect my carpet from chair feet, I have kept them in part because my carpet is more important than the look of these rugs and in part because returning them would be pricey.
