These are waist straps made from a new, genuine silk (正絹) nagajuban (long undergarment). They are 3.5 cm wide and 290 cm long, and there are three of them. These waist straps are made of genuine silk, and the sound of the silk sliding against itself is pleasant. Recommended for those with a 1-meter waist or those who are a bit plump. Please forgive any threads or other debris that may be attached to the fabric.
