This is a ring sling from the Danish brand Löft. I purchased it through personal import in 2022. I've only used it for about three months with each of my two children, so it's in relatively good condition. There are no noticeable scratches or stains. It has been washed and ironed. Two rings are sewn on. It's made of breathable, firm natural materials, making it recommended for summer. It looks gray in the photos, but the color is a slightly yellowish mint green. Material: 40% organic hemp, 60% cotton There are no instructions, so please refer to the brand's official website for how to use it.
