Marker is one of the teacher's go-to school supplies. Her work is tip-top, and she always makes a lasting impression. That is, until Pinking Shears, a.k.a. Pink, arrives and dazzles everyone with her sharp creations. No longer the star of the desk, Marker begins to make mistakes. The trouble is, they can't just be erased; her work is permanent, and she's not allowed to fail. Or so she thinks...until a realization helps her rediscover her Marker magic.
