Hozosao shamisen Itomaki

Does anyone know if it’s possible to buy itali that isn’t sized for tsugaru shamisen? I have a Hozosao shamisen and I found the glowing itomaki. It looked so cool!

They pop up on Ebay every once in awhile, usually in mismatched sets of six. If you have access to woodworking equipment, you could make your own. This video may help: https://youtu.be/pOyJxbp2NRM?t=3m23s
