The sticker on the back is missing, so the exact year of manufacture is unknown. However, it was purchased by my nephew, who was born in 2018, and I received it from him, so I believe it's from 2018. There is a deep scratch on the top panel, marked in black in the last image. It doesn't show up well in the reflection, and you won't notice it unless you look closely. There are also some stains on the main body. The back has particularly noticeable stains. The operation has been confirmed and there are no problems. The instruction manual, box, mat, and batteries are not included. Please use four AA batteries. I do have a mat, but it has strong creases and is also stained. I can include it if you still want it. It has been disinfected. I will wrap it in bubble wrap and package it with materials I have at home. Please refrain from purchasing if you are concerned about minor details.
