Purchased new from the Konny website in June 2025. The size is 6M, which I believe is around 70-80cm. It's made of a soft material that dries easily after washing. It was very useful as it allows you to take your arms out, which is helpful for practicing graduating from swaddling. I used it for about 3 months, and I am selling it because my baby started to roll over. There are no noticeable stains, but please understand that this is a used item before purchasing.
