21 Inches of Thick Rich Brunette Virgin Hair

Totally virgin hair. No treatments whatsoever.
The hair has a lot of color to it. There’s definitely some red undertones but there’s also a lot of natural highlights. My hair lightens up in the sun significantly but I haven’t spent much time in the sun for the last few years. This is 4 years of growth with a handful of trims in that time.
Extremely healthy lifestyle with daily supplement use including collagen and healthy fats. Not a smoker. For two years I have only washed my hair once a week with spring water, no tap water. Heat use less than a dozen times. I only use clean and nontoxic products.
At the base of my ponytail the circumference is 3.5 inches. I do have some layers that fall just about half way down the ponytail and under those the ponytail is 2.5 inches thick.

Preferred payment method would be PayPal and I am open to any shipping methods.
