If you’re the type who eats Chinese food regularly, you no doubt have your own chopsticks. But where does one put them? How do you carry them around? Now they’ll be handy wherever you go. They will be stowed in your glasses.
Never be without chopsticks again. Just pull them out and start eating. You can also use them to hold your hair back, but if you do both it’s going to get messy. I suppose they are also handy as weapons should you need them. Even a stylus.
