Purchased at the end of 2021. Since my parents' home was far away, I kept this at their place for my use. ☺︎ I only went home once a year for about a week, so I used it then. The total usage is countable. I mainly used it on sunny days for walks nearby and indoors at shopping malls, etc. ☺︎ I think the frame is in good condition, without any noticeable scratches or scuffs, but it has been handled by someone, so please check the condition in the photos. ☺︎ When not in use, I wrapped it in bubble wrap and stored it indoors. Also, there is no history of leaks or vomiting. It was used and stored in an environment without pets or smokers.
