What does toothpick mean?

Describe a boy as thin as a toothpick.

A toothpick, usually a small stick with one or two tips, also has a hook-shaped front end, and the pointed toothpick can be broken at the front end to support the toothpick head.

The toothpick is hard, smooth and burr-free, with a slightly thinner top, but not too sharp. They will not change color and taste after being soaked in water, and their tips will not soften. Some inferior toothpicks with different brands in the market will be bleached with industrial hydrogen peroxide, which is very harmful to human body. It is recommended to use high-quality goods from regular manufacturers, and try not to choose unnatural goods with white toothpicks.
