Works but not very vibrant [SEP] I got these specifically for the red and green for the Christmas holiday. They're fairly small, but easy to handle. But no matter how hard I pulled it against my hair I simply wasn't getting the color that I wanted. My hair is very blond/white/grey so normally any kind of this coloring stuff goes on easy and stays a long time with bright color. I bought it especially for the green because other brands are more Grinch-green and this looked like it was going to be a true Christmas green. But it just didn't adhere to my hair very well (and I dampened it as per the instruction). I'll play with it a bit more on my white dog, so I'm sure I'll get use out of it, and for the money I paid I didn't lose much!
