I've never used this; it's been sitting in my closet. As shown in the last image, it was folded in half lengthwise and hung on a hanger, so there are fold marks when unfolded, but it has not been used. The flat, vertical size measurement is doubled because it's folded in half. This is a stylish muffler, typical of CASTELBAJAC. Thank you. - Brand: CASTELBAJAC - Size: 40 - Color: Blue - Design: Question mark pattern - Embroidery: Logo embroidery - Fringe: Yes Thank you for looking.
