This is the current model. I purchased it last year and used it for about 3 months. The color is black. I cannot answer detailed questions about frequency of use beyond what is stated. The rubber has some creases, but it's not stretched and can be gathered. The buckle is also in good condition. 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. Only the items in the images will be shipped. It has been home-cleaned, but I have not used organic detergents or baby laundry detergents. If you are concerned about minor details or are a perfectionist, please purchase a new item. As I am a private seller, there may be oversights. Please only proceed with the transaction if you understand that this is a used item. It will be folded and shipped, so please be aware of potential wrinkles. * Only the items in the images will be shipped. Accessories not shown in the images are not included. * It will be shipped using two A4 or A3 size宅配用ビニール袋 (shipping 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 have included this information to avoid trouble, as I received a negative review due to damage caused by opening with scissors. If you would like excessive packaging, I can accommodate you for an additional fee, so please comment.
