I purchased this item used and have been using it for three years. I hate to throw it away, so I'd like to give it to someone who can use it. It can be shipped in a 160cm box, but it will cost a bit extra, so I'll sell it cheaper to those who can pick it up. Feel free to comment if you're interested. After use, I wiped the main body as clean as possible. All fabric covers have been washed. The baby booster has some original white stains that I couldn't remove. I stored the baby part without using it. I apologize, but I have lost the instruction manual. It's suitable for children aged 0 to 4 years old. It can be used both forward-facing and rear-facing. Installation is easy. Please understand that there may be some remaining stains as it was actually used by a child for several years. I have a dog. Dog hair tends to stick due to static electricity. Please purchase only if you don't mind. Non-smoker. Pick-up is possible around Higashi-omiya, Minuma-ku, Saitama City. I'm looking forward to your comments.
