OMNI 360 Cool Air Classic Weave Age: 0-48 months, 3.2-20kg Material: Body: 100% Polyester Baby Waist Belt: 100% Polyester Size: Fits waists up to approximately 132cm I purchased this on Mercari!! The previous owner seems to have bought it from an authorized Rakuten retailer. There are no noticeable stains or tears. I think it can still be used. I would like to sell it to someone who will take good care of it. This is a used item, so please purchase only if you understand this.
