Bu Jin has partnered up with Aikid24. They do have a limited stock of items on thier web site, but they are slowly getting more each time I look. If you do not see your size or what you want contact them and they may be able to help you. I have contacted them and they got back to me pretty quick. I spoke with them on the phone and they were able to help me out with what I needed.
Shoot them an email!
