The tujlub is made of some type of plastic, and I do not remember the type of plastic. I just uploaded a video on "How to Spin a Tujlub". I will make a video on how to throw a tujlub sometime next week. If you are interested in playing tujlub, contact the person I posted on the forum. Tell him the size you want and he will make a tujlub for you. Once you have your very own tujlub, watch the videos and practice. The Hmong community in Minnesota and Wisconsin hosts the biggest tujlub tournament in May, July, and September. It will only take from 6 months to 1 year in order to know how to play tujlub. Make your own team and come play with us at our tujlub tournament for big money prizes!
