Thick brown virgin hair

Selling my thick virgin medium brown hair. I never use heat on my hair and use sulfate-free shampoo and conditioner. Washed about every three days and use a hair mask once weekly. My hair is a medium brown- in the light, it has some blonde/auburn highlights and has a slight wave to it. It is VERY thick… I constantly get told this! Right now it is about 15 inches of hair I’m willing to sell.
