Toothpicks are sometimes enclosed with the disposable chopsticks that are provided free of charge when you buy food at convenience stores and supermarkets.

Disposable chopsticks wrappers are often marked with a large diagram to indicate if toothpicks are included, so check before opening the package. These days, they are often packaged in a transparent wrapper, so you can check what's inside before opening the package.

If you use the tip of the disposable chopsticks to pierce open the wrapper, the toothpick inside may come out of the wrapper with force and injure your fingers. Open the wrapper carefully, and watch out for the toothpick.
