When wood pencils just aren’t enough. These became popular roughly in the 2nd grade, kids would screech over these. A long thin piece of graphite, commonly found in the 0.3 to 0.9mm range. Finding one of these on the floor, especially when there is a lot of led inside of it is a status symbol of clout and wealth within the school walls. Kids will also cry when they loose one. Consider it your lucky day if you find a loaded mechanical pencil on the floor. You can buy a few pencils for one if you’re lucky! These are the best writing tools you can get access to, and since no one buys them, it may take a while to get one.
Kid: Dude, I just found a loaded mechanical pencil.
Other kid: How much led is inside?
Kid: 4 full sticks bro.
Other kid: Lucky! Toss me one?
Kid: Gonna cost you some cash brother.
