Product Description: Brand/Manufacturer: Nittai Roadman Co., Ltd. This is an item from a while back. It was originally the designated bloomers for a certain high school. It has a gentle, wrapping feel around the hips. Model Number: 1580 Size: L Waist: 66 cm Material: 100% Polyester Made to be large. It's about the size of a 2L from other manufacturers. Since it's for school use, it's made sturdy. It can also be used as a "misepan" (undergarment worn to prevent exposure), and My daughter wears it on her period except in the summer. Because the fabric is thick, it's warm and holds firmly, so she says it doesn't slip, and she loves this product. It's currently discontinued and difficult to obtain.
