The size is 86cm, which is generally for children aged 1 to 1.5 years old. Overall, it's in good condition, but the material seems to be vinyl or water-repellent (I'm sorry, I'm not sure of the exact fabric type). It's a smooth fabric that scratches easily, and there are stains and scuffs around the buttons (see photos). There's also a puffed-up area on the back. Shipping will be via Yu-Packet Post. Returns are not accepted, so please understand this before purchasing.
