I received this item new and used it about 3 times. I cannot answer detailed questions about frequency of use beyond what is stated. There are bite marks on the ring. There are no noticeable scratches or stains, but this is based on my personal assessment. Please only purchase if you are satisfied after confirming the images. I do not have any pets, and I do not smoke. I will only ship the items shown in the images. The item has been home-cleaned, but I did not use organic detergents or baby laundry detergents. If you are concerned about minor details or are a perfectionist, please purchase a new item. Since I am a private seller, there may be oversights. Please only proceed with the transaction if you understand that this is a used item. I will fold the item compactly for shipping, so please be aware of potential wrinkles. * I will only ship the items shown in the images. Accessories not shown in the images are not included. * 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 the package with scissors. I am writing this to avoid trouble, as I received a negative review because the item was damaged when opened with scissors. If you would like excessive packaging, I can accommodate you for an additional fee, so please comment.
