I purchased this but stopped using it after only a few times and have been storing it. There's still plenty of room even with diapers and wet wipes inside. The seat and the inside of the shoulder pads have non-slip material. There's a slight fraying on the inside, but it's in good condition with no noticeable stains. Please check the photos. Please understand that this item has been stored at home with small children before purchasing. - Brand: Hugoo - Color: Black - Waist Bag ● Color Black ● Size Overall width: Approximately 28.5cm Height: Approximately 16.5cm Depth: Approximately 10.5cm (Capacity: Approximately 4L) Weight: Approximately 430g Retail price: 13,500 yen
