Thank you for viewing. This is a baby playpen used for 3 months. I checked the Nishimatsuya website, etc., to confirm the size and details of the product, but I couldn't find a product page that matched the size of this product, so the size is based on amateur measurements. Please understand. Size: Approximately 170cm (length) x 120cm (width) x 60cm (height) Target age: 5 months to around 3 years old [Color] Silver Gray Please note that there may be overlooked stains. Regarding assembly, it is common to the soft baby circle series, so please refer to the instruction manual. https://www.24028.jp/user-src/product/common/pdf/original/manual/indoorgoods/softbabycircle-square.pdf
