Saw this on kickstarter, a little stick to wrap your headphones on. He's got 67 backers so far, probably an average of $8 - $9 each. Nice little profit for what is involved in cutting two angled kerfs, dividing up into sticks, adding round overs, and branding. Doesn't mention a finish other than sanding, but a quick lacquer or seal coat wouldn't add much time. Postage for most would be $3 or so, so I guess it's getting down to minimum wage, but key would be mass production to save on time and raise the profit.
