Almost unused. Product Description From Lotte, the makers of the disposable "Hokaron" body warmers, comes the "Kiru Hokaron" (Wearable Hokaron)! This padded vest is perfect for cold winters, offering excellent warmth! As a countermeasure against "cold backs," which can cause poor circulation, the back is made with heat-retaining padding. It's a plus that it can be washed at home using a laundry net. It's also easy to wear as an inner layer under a jacket, making it a convenient item to have for cold protection.
