This is a black child seat made with mesh material. - There is one scratch. It's on the bottom right when facing the seat. Please check images 16 and 17. Other than that, I think there are no noticeable stains or dirt. - There is no fix guide. I installed it without using it. Please check images 18 and 19. For those who understand that this is a used item, how about it? - Brand: AILEBEBE - Color: Black - Type: Child seat - Design: Mesh material
