What? Bra Developed Which Only Opens for Woman's "True Love"

There have been some pretty wild products to come out of Japan over the years, but this bra which purports to only open for "true love" has to be one of the strangest yet.

Developed by Japanese company Ravijour, the "True Love Tester" bra features a "built-in sensor [which] reads the woman's heart-rate signal and sends it to a special app via Bluetooth for analysis," according to the product designer. "The app then calculates the True Love Rate based in changes in the heart rate over time."
