I'm not sure if the title is correct. This product is 100 pieces of the hook and key chain parts shown in the red circle in image 1. (Hooks only) Please check the size in the image. (Calipers are not included) How about this for those who make keychains, etc. by hand? I stored them after removing them from new items, so I think they are clean, but since they are stored by an amateur, there may be some scratches or damage, so please understand. Other sets are also possible. 50 pieces 950 yen, 100 pieces 1600 yen, 150 pieces 2200 yen, Shipping will be on weekdays excluding Saturdays, Sundays, and holidays. They will be placed directly in a box without packaging, and will be sent via Yu-Yu Mercari. (Please understand that the packaging box may be dirty) If you understand all of the above, you can buy it immediately. Thank you.
