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 top of the tail fluke it is just a touch over 6 1/2 inches long and just a touch under 17 cm.
