I bought this, but I rarely used it in class, so it's a complete set. Grease unused No marks or names written There is a small chip on the mouthpiece. It does not affect use. See photo 5. Because I commute with a backpack Some parts of the printing on the storage case are scuffed. See photo 6. After cleaning and alcohol disinfection, I will ship it anonymously via Yu-Packet Plus. I would appreciate it if you could purchase it if you are not concerned about minor details and understand that it is a used item. ⭕️Instant purchase ⭕️Ships within 24 hours
