Alert Napkin / napkin

Alert Napkin
Alert Napkin

Will it be annoying if you’re about to use the toilet paper when you suddenly find that it’s almost used up? Blaming yourself or paying constant attention to the paper is not a good solution. Now Alert Napkin provides you with a new one. The difference between Alert Napkin and regular napkin is that its innermost layers are colored in red, as an alert that the paper is running out. Therefore the user knows that it’s time to replace a new one in the napkin box and the problem we mentioned at the beginning will be no more.
