Ever wonder why picking sticks in his teeth, one side grooved?
There are certainly bilateral wand, but it will be discussed on toothpicks with grooves.
The fact is that familiar to us the bilateral toothpicks are "European". Because almost everywhere in Europe have ashtrays and do all things with a toothpick you safely throw it in there. While Japan is not (Well, no, we're talking about how everything turned out) and put "work" toothpick and spoil her desk is not well. To solve this problem is those grooves. You break off the edge and put a toothpick at him, so she did not touch the tip of the dirty table.
