I purchased this about three years ago and used it for about a month. I cannot answer detailed questions about frequency of use beyond what is stated. There are no noticeable scratches or stains, but this is based on my own assessment. Please only purchase if you are satisfied after checking the images. I do not have any pets, and I do not smoke. I will only ship what is shown in the images. It has been home-cleaned, but I did not use organic detergents or baby laundry detergents. If you are concerned about minor details or are very particular, please purchase a new item. Since I am a non-professional, I may have overlooked something. Please only proceed with the transaction if you understand that this is a used item. I will fold it up small for shipping, so please be aware of possible wrinkles. * I will only ship what is shown in the images. I am not selling any accessories that are not in the images. * I ship using two A4 or A3 size shipping plastic bags. I do not use cardboard boxes or dedicated shipping bags sold by delivery companies. * Please be careful when opening with scissors. I have included this to avoid trouble, as I received a negative review because of damage caused by opening with scissors. If you would like excessive packaging, I can accommodate you for an additional fee, so please comment.
