I bought this four years ago, but I haven't used it much, so it's in pretty good condition. I think it cost over 10,000 yen when I bought it. It can be used from toddlerhood up to around the third grade of elementary school. The ones sold at home centers for 2,000 or 3,000 yen break down quickly. I recommend a sturdy one that will last for several years! Note: Leash cord is not included.
