Purchased in October 2023. It has been used to a certain extent, and there are scratches and stains (photos 6, 7, and 8), but I think the condition is relatively good. It comes with the optional linear seat. Photos 1, 2, 9, and 10 show the state with the linear seat attached. Photo 12 shows the state with the linear seat removed. I remember using the linear seat a few times. I cleaned it, but there is fine dirt that has gotten into the mesh holes (photos 3 and 4). Instruction manual included. For those who understand that this is a used item, thank you. Will be shipped in simple packaging (bubble wrap).
