Used about 3 times and washed, so there are no noticeable stains. Retail price: 2420 yen. I am a non-smoker and do not own any pets. I am not considering any discounts. Please feel free to ask if you have any questions. The following is the manufacturer's description: Wear it actively for sandbox play or camping. The shoulder straps are elastic, making it easy to put on and take off. Water-repellent finish repels water and dirt. The elastic cuffs prevent sand from entering. Comes with a storage pouch.
