Purchased on November 26, 2025, one month ago, and only used once. Selling because I'm switching to a double stroller. I disposed of the original box, so it will be shipped in a KATOJI box. The main body, instruction manual, and genuine seat liner are included. Regarding the warranty, I registered for the 3-year warranty immediately after opening it, so I'm not sure if the warranty will transfer to the buyer. It's in very good condition!
