I know that you should, theoretically, wash your delicates separately, but I never thought of owning something like the Mr. Klein Washing Machine. A washer created exclusively for underwear, it will encourage you to treat those closest to you (literally) with the proper rinse cycle.
Using reused, reusable water, the Mr. Klein Washing Machine by Yoon Kisang doesn't sound too appealing. Apparently, however, that's the best way to get those undies clean. It's an eco-friendly option at the very least.
