This is the Britax Römer ADVANSAFIX IV R. It can be used from newborns to around 4 years old. It is ISOFIX compatible for easy installation. There are some minor scratches and stains from use, but it is generally in good condition. There are no pets or smokers. There is a small stain on the belt, see the last photo. I am selling it because I no longer need it. Retail price is 68,000 yen. [Brand] Britax Römer [Product Name] ADVANSAFIX IV R [Color] Gray Thank you.
