Nishijin - Gold Leaves Kinran Broach
This is made from Japanese kimono obi, called kinran. Golden threads are used. That's why it is so glittery! This is Nishijin Ori, special kimono fabric from Kyoto. Also, this is double layered with a fabric called chijimi, fluffy silk used for kimono or yukata (summer kimono) obi.
A safety pin is attached to it. You can put it on anywhere on your clothes.
