KNOTTED OBI BELT Whether described as a leather obi belt, leather tie belt, sash belt or wrap belt, these are all the same design. Wide belts that you wrap around and tie either at the front, back or side - obi wrap belt style from Japanese origins. These obi belts / tie belts look divine in all modes described above. If you put on weight or lose weight you don't have to fret about fit how you do with a buckled belt. The soft leather obi belt is more flexible so can also be worn as an obi hip belt - a hobi belt!
