The actual item has less yellowing than the image. This is for one item. I don't think there's any unpleasant smell. It feels like an air freshener is waving at you from afar. I will flatten it to fit through the post slot for packaging. Please be aware that the label may be creased or the wrapping may be loose. It will be sent via Yu-Packet Post. If it can be combined with other items, I will deduct the shipping cost.
