Hey Japanese guys, trying to get to second base? You better have an engagement ring.
There are so many unanswered questions, but this site writes:
“The bra itself looks like everyday lingerie with the exception that it is fitted with an LED display underneath the cups. Just above this display is the handy storage slot for an engagement ring.
In theory, the timer will be set to the expected date of marriage for the wearer. It will tick away, only to stop when the engagement ring slides into the allocated slot.”
WTF? I’ve attached a video, but it’s of no use, really, unless you understand Japanese. I guess there is also a pen and stamp included as to help expedite the wedding certificate process.
