If you’re like me, you’ve just been throwing away your fingernail clippings like a shlub. However, if you’re someone with “business mindset,” you know that each finger contains a slow-growing, keratin-filled gold mine — and all you need is the right buyer.

This is where the odd world of “online fingernail clipping salesmen” comes in. According to Kankan News, one woman recently went viral after selling her fingernail clippings for about $21 USD per kilogram. Per Kankan News, she had been collecting them since childhood.

But why does anyone want fingernail clippings? The answer, it seems, is “traditional Chinese medicine.” Some say that fingernail clippings are essential in making concoctions to treat conditions like abdominal distension and tonsillitis — and, seeing as human adults only produce about 100 grams of fingernails per year on average, getting enough to actually use may require one to buy some from an online fingernail salesman.

So, if they won’t let you sell any more plasma and you’ve already auctioned off your kidney, don’t worry — there’s still plenty more of your body that you can sell!
