Hi, How much does this item sell for? are there different types? How can I make one? * It is hard for me to describe but it is a a small bag that you can put on your wall and it is filled with beads or rice or something soft yet firm. Kung fu guys use them to punch into I think. size is probably 30cm by 30cm
Just google "iron palm training" and you'll get lots of sites selling them. I bought some many years ago when I was taking kung fu - mine was filled with crushed granite, and if I remember correctly they're pretty damn inexpensive.
