This is a anti-burglar doormat from Rakuten.It features a super-sticky mat that will stick to the burglar.
When you leave the house, you just leave this on the inside of your door. If someone breaks in, they'll step on the mat and get stuck.
One thing! You can't forget it's there when you come in through the door! If you do, you'll be stuck!
The anti-burglar doormat will be released in Japan sometime this fall.
