These metal jigs are all slightly bent, hence the price. The contents of the items are: Jack Eye Makimaki 40g x 2 (orange and pink) Jack Eye Makimaki 30g x 1 (red) Zeake x Tsulino Jig 30g x 1 (yellow-green) Regarding usability, there was not much difference. As shown in the photos, all the jigs are bent, so please purchase them if you understand this. If you have any questions, please feel free to comment! Thank you for looking!
