He is tall, wears yellow clothes, and has red eraser shoes. He has a light brown face and free-spirited hair as black as graphite! He's a mischievous but kind guy. He's a newcomer who hasn't been in the pencil case for long.

He used to have fair, white skin, but because the owner kept using him, he's now all worn down with black graphite marks everywhere. Since he's used so often, his body sometimes breaks (or he might disappear forever...?). He has gone completely insane due to the trauma of the terrible things the owner has done to him.

Quite tall at 15cm. He has a transparent plastic body with blue scales engraved on it. A pretty blue flower is also engraved on his body. He's the longest survivor here, so he's seen everything his friends have gone through. However, he has become numb over the years. A total 'T' (Thinking) type. He always prioritizes facts, but he takes good care of others.

His ink is drying up and he's almost used up. He lives in constant fear, thinking he might be thrown away since his lifespan is nearly over. He has an anxious attachment style and is always wary of his surroundings. He has a timid personality. However, he knows a lot, so he's fun to chat with.

She is mainly used for grading. She is the only piece of stationery the owner cherishes and takes care of. This is probably because the owner intends to use her until he goes to college. She has a transparent plastic body with a core made of red wax inside. She can be quite kind, but she gets hurt easily by others. You could say she's a bit of a high-maintenance girl.

A vivid yellow highlighter. It's not actual bioluminescence, but looking at his face when the cap is off makes other stationery feel dazed. He wears a yellow cap like a hat to hide his face. He wears a long, black plastic outfit. He is always hopeful and positive. Sometimes it's so excessive that it's scary.

He has red, blue, and black ink. He is being used usefully, and since his ink can be refilled, he is expected to survive for a long time. He has a relaxed and carefree personality. He is calm and stable. However, he becomes diligent when a crisis arises.

The biggest guy here. He's in a position that could be called the leader of the pencil case. However, due to his eccentric and attention-seeking personality, he's not a very good leader. In fact, he often gets ignored. He has white handles and a body made of metal. Usually, he wears a white plastic protective cap. On the outside, he is rough and always angry, but in reality, he is very delicate and has a fragile, glass-like mentality. He keeps this hidden.
