This Lady that runs this site can make custom Nunchaku cases. http://www.thehakamalady.com/She can make any case you want and her hakamas are great too.
Sorry if I missed something, but are there any pictures of the actual products that aren't drawn with markers?
I got tired of having to carry all my chuks when I went places so I decided to buy a Nunchaku Caddy and give it a try. I had to get the large model though they do come in smaller sizes and other colors. I can pack up to 24 pairs without a problem and it comes with a guarantee that you will never have your chuks stolen, although they may get chewed once in a while. The best feature is that when you throw your chuks at a target, there is an auto-retrieval built in. All in all its a very good buy.
