LOVE, LOVE, LOVE these darling carpets. They came packed so neatly. In a zip bag folded into tiny squares but when you open the bag, ta da... a beautiful fluffy carpet X2. Love them. Perfect color, great in bathroom, dries easily and washed superbly. I highly recommend.

positive

Wow! And not in a good way. I had color treated hair and was looking for a slight tint to cover my grey....well 3-5 minutes later I'm left with bright red hair ONLY in the places that were dyed blonde. Don't not cover any other places. AND stripped all my other color away.

Ex Output:
negative
