You can buy nose prosthetics in vending machines in Japan now. So all nose picking enthusiasts can pick to their hearts content and leave no mess! They’re only $2 and come in in four styles and two colors and make a 'suction-pop' noise once the user removes their finger from the nostril.
One model even includes fake boogers to make the experience even more enjoyable. We’ll just stick to doing it the old fashioned way and flicking out our car window on the expressway.
