Hi all! I buy this particular air freshener not for the first time, I always take a large package of 10 pieces plus a couple of pieces in the collection! enough for about a month but I change every 3 weeks for a fuller and more lasting fragrance, I love this smell and all the passengers who get into my car always say: what a cool smell here: in this way I achieve several positive points! I definitely recommend this brand as it has been produced for decades and is known all over the world where people love Japanese cars! Thank you Japan for your high quality products from air fresheners to cars and beyond! I love you sincerely, your Kazakh fan living in the USA! 有難うございます！
