The columnar packaging of the toothpick is made of plastic paper. The whole column of toothpicks can be put into the toothpick holder only by tearing off the upper part of the packaging paper, which avoids the problems of easy creeping down and inconvenient dropping into the holder when using traditional toothpick package, thus facilitating our living way.
