K18 rope chain ring. It has a twisted design. As it's a chain ring, it should fit those who wear sizes #17 to #19. The size is 19, and the width is about 2.4mm. The weight is about 0.6g. It has been lightly cleaned. Returns are not accepted to prevent switching. Please check the images and purchase. I am also selling on other sites, so I may delete the listing, so don't delay! Please inspect the item upon arrival and only purchase if you can promptly confirm receipt.
