Hand bent with aluminum wire. Each one is slightly different because I do not use a jig. You can order more here. They will be quite similar. If you just order one this is the one you will get in the picture or one so close you might not even notice.
From the tip of it's nose to the end of the tail it is 6 1/2 inches long or almost 17 cm.
You can see from the second photo just sliding the hook back allows you to hang your fish sideways... more in the swimming position
