Coon tail?
Do you mean making like a coon tail? [That's what we call it in the U.S.]
Like, it's horizontal stripes down the hair?
I don't know where you can purchase them, but I know how to make them.
You take an extension [any color you want], tape it down to cardboard.
Then, you take tape, and put it over the spots where you don't want it to have the color of your striped part.
Then, you take the hair dye color you want the stripes to be, and just dye the exposed parts that color.
And, that should do it [make sure to follow the amount fo time you leave the dye in for, follows the directions on the box!]
