Purchased in October 2020. Used only indoors. I bought it to use for putting my baby to sleep, but since I ended up co-sleeping most of the time, I've only used it about 5 times. It has been washed once in a net. After that, it was stored in a closet. Usable up to 20 kg. Currently 13,200 yen on Amazon. There are no noticeable stains or scratches, but please refrain from purchasing if you are concerned as it is a used item. The box and instruction manual are not included. Gender: Unisex
